📚 供应链管理的魔力:MIT的'供应链前沿'
MIT的'供应链前沿'节目由MIT运输与物流中心呈现,旨在深入探讨供应链管理、物流、教育等话题。本期节目邀请了CTL主任Yossi Sheffi和'供应链季刊'执行编辑Susan Lacefield,共同讨论Sheffi教授的新书《魔法传送带:供应链、人工智能和工作的未来》。节目还介绍了MIT CTL提供的教育项目,旨在为不同层次的学生和专业人士提供供应链和物流领域的深入学习机会。
🔍 供应链的复杂性与未来的挑战
在对话中,Sheffi教授首先解释了为何撰写《魔法传送带》一书,旨在普及供应链的概念及其复杂性。他强调,尽管疫情后人们对供应链的讨论增多,但对其理解仍然有限。书中第一部分解释了供应链的复杂性,以及为何当产品出现在货架上时,人们应感到惊奇而非理所当然。接着,讨论转向供应链的日益增长的复杂性,Sheffi教授认为,由于不可预测的事件和技术的发展,复杂性将持续增长,而非减少。
🌐 去中心化供应链的风险与效率
对话进一步探讨了供应链的去中心化问题。Sheffi教授认为,尽管去中心化带来了风险,但从宏观经济角度来看,风险实际上是降低的。他以纽约的餐饮业为例,说明了高度竞争如何保证整体质量,即使单个企业可能面临更高的风险。此外,讨论还涉及了供应链的深度和可见性问题,以及技术如何帮助改善这些问题,尽管完全的透明度很难实现。
🤖 人工智能在供应链中的应用与前景
Sheffi教授和Lacefield女士讨论了人工智能(AI)对供应链的影响,特别是生成性AI的兴起。Sheffi教授提到,AI在风险管理中的应用,如通过大型语言模型分析供应商的风险,以及AI如何帮助实时监控和警报系统。他们还讨论了AI在供应链中可能导致的更多复杂性,以及如何在经济压力下简化流程。
🚀 AI的伦理和社会影响
在讨论AI的应用时,Sheffi教授表达了对AI可能被滥用的担忧,例如制造假新闻或指导制造危险装置。他指出,尽管存在这些风险,但社会各界已经意识到这些问题,并正在采取措施来防范,如在AI系统中设置防护措施。此外,他还强调了未来工作中监控和审查自动化的重要性,以及如何训练人员来执行这些任务。
🤝 人际关系在供应链管理中的重要性
Sheffi教授强调了人际关系在供应链管理中的重要性,尤其是在处理突发事件和确保供应商理解买方需求时。他通过福特汽车因缺少小零件而无法交付车辆的例子,说明了关键供应商的重要性。此外,他还讨论了AI如何帮助识别哪些供应商值得建立人际关系,以及如何避免在技术项目中本末倒置,即从问题出发,而非从技术出发。
🎓 供应链管理教育的演变
Sheffi教授讨论了供应链管理教育的变化,强调了软技能的重要性,如沟通、销售和团队合作。他提到,随着AI和自动化的普及,软技能将变得更加重要。他还提出了对教育系统进行改革的建议,比如采用德国的双元制教育模式,以及如何让学生理解AI的能力和局限,成为AI系统的熟练使用者。
🛠️ 技术进步与就业市场的变迁
在最后一段中,Sheffi教授讨论了技术进步如何导致某些工作的消失和新工作的创造。他用AT&T自动电话交换机的发明和它对电话接线员工作的影响作为例子,说明技术变革对就业市场的长期影响。他还提到了3D打印技术对供应链的潜在影响,以及需要更全面的系统思维来解决如稀土矿物供应等全球性问题。

- Welcome to MIT's "Supply Chain Frontiers,"
presented by the MIT Center
for Transportation and Logistics.
Each episode of "Supply Chain Frontiers"
features center researchers and staff
or experts from industry
for in-depth conversations
about supply chain management,
logistics, education and beyond.
(upbeat music)
Today's episode features a conversation
between CTL Director Yossi Sheffi
and Susan Lacefield, executive editor
at "Supply Chain Quarterly."
Today's conversation was recorded
in front of a live audience
and covers a wide range of topics
touched on in Professor Sheffi's latest book,
"The Magic Conveyor Belt: Supply Chains,
A.I., and the Future of Work."
But first, MIT CTL offers a variety
of educational programs for graduate students,
seasoned industry professionals
and anyone at any level looking to learn more
about the supply chain and logistics domains.
To find out more about all
of CTL's educational offerings,
visit ctl.mit.edu/education.
And now, without further ado,
here's what makes the magic conveyor belt so magical.
- Maybe a good place to start
is with the title of the book.
Can you explain the analogy
you make between the supply chain
and the magic conveyor belt,
and what makes it magical?
- So let's start with why
I wrote this book.
After the pandemic,
a lot of people
were getting to my wife
(Susan laughs) and asking her,
"We understand your husband is in supply chain.
What is this?"
And imagine if, even after the pandemic,
people heard a lot of supply chain,
didn't know what it is.
So rather than having one-on-one interview
with one of the several hundred friends
that my wife has, I decide
(Susan laughs) to write a book.
So the first part of the book is explaining
what supply chains are,
why they are complex and, in some sense,
why would people should not
be pissed off when something
is not on the shelf or not available
on Amazon, but should be amazed
and awe-inspired when it's there.
Once they understand what it takes
to get something from the mines
in China or somewhere
to a finished product on a shelf,
how many processes it has to go through,
how many people are involved,
how many different tax regimes,
custom regime it has to go through
before we get the final product.
So this was the rationale.
And the magic convey belt is because
once you understand what it takes,
you think it's magic.
- Mm-hm, and it's very true.
- That's the title. - That's true.
So it was to get away from people asking you
why their cat food-
- Yeah, absolutely. (Susan laughs)
Absolutely. (laughs)
- So as you mentioned,
the first part of the book really talks about
the growing complexity of the supply chain
over the past few decades.
And I was wondering,
do you think we're gonna reach a point
where companies are gonna push back and say,
"Things are getting too complex"
and we need to maybe take a step back
and look at simplifying?
Or is complexity here to stay?
- I'm not sure.
I think complexity is here to stay.
Complexity is here to grow
because of unexpected event that's happening.
And furthermore, I'm not sure
there's a pressure to do it because a lot
of the technology that is being available
help company deal with the complexity
and deal with the unexpected event.
So I'm not sure there's a pressure to do it,
especially among large, sophisticated companies.
So the answer is no. - No.
(Susan and Yossi laugh) - It is here to stay.
(Susan laughs) - Here to stay.
- You talked about one of the most mind-blowing facts
about any product that we touch
is the thousands of organizations
that have been involved in creating it,
and that they have done that
without any central control.
And I was wondering if decentralization is,
do you feel that's crucial
to supply chain efficiency and operating
in this complex world?
- Categorically, yes. - Okay.
- The idea that somebody can control,
control of supply chain is controlling the economy.
We tried it once or twice.
Didn't work very well.
So we're talking about modern markets.
Supply chain is actually
a whole set of buyer-seller,
buyer-seller, buyer-seller negotiation,
transaction, operation.
It works because everybody's trying
to do the right thing to minimize costs
and maximize level of service, by and large.
Now there are other things people
are worried about, like sustainability
and resilience, but everybody is worried about it,
so everybody's trying to get
the best outcome.
I don't see how central planning can work.
Even in China, we don't see,
it's not central planning.
Central control of certain aspects,
but not of the transaction.
In fact, the Chinese
seem to be leery of very large corporations
who control more of the larger part
of the economy.
Has happened to several, you know,
tech companies in China.
They actually seem to encourage
competition between companies.
So I think it works, the market works.
- But as you introduce decentralization,
there's an element of risk
that kind of enters the equation.
I was wondering how do we balance that risk
with all the benefits?
- No, it's, au contraire.
The risk goes down. - Huh.
- Because the risk to a particular company
maybe goes up.
They are out there on the front line.
But the risk to the economy- - Ah.
- Goes down. - Okay.
- Look, you can always find
good restaurant in New York, always.
You walk to a random restaurant,
the chances are it's a very good one.
Why?
Because restaurants in New York,
if you open a restaurant in New York,
the chances are within a year,
you'll have to close it.
The competition is murderous.
There are so many good restaurants.
So you can say the chances
for individual restaurant to succeed
is not very high.
But going to New York and having a good restaurant,
you know, the environment is great.
It works.
There's no risk.
You don't risk going to New York and not finding
a good place to eat.
I'm not saying a place to eat, a good place to eat,
because it is decentralized.
- But there is, when you outsource
to a supplier and they're outsourcing
to other suppliers, there is that added risk
of, you know, a quality defect
that you can't control
or a sustainability issue popping up.
Is that a concern with this decentralization?
You know, how do you control for that sort of?
- I don't see it as a decentralization issue.
- Okay, okay. - I see it
as the depth of the supply chain,
the lack of visibility.
It exists.
It get slowly better with new technology.
But there are limits here.
The limits are that
for suppliers to tell their customer
who their supplier is,
not every supplier is willing to do it.
It's a competitive advantage
to know who the suppliers are.
And there always the fear
that the customer will go around them,
will go directly to the supplier.
So there's a kind of built-in opaqueness
to the supply chain,
which we're trying to get through to visibility
and good relationship and all of this,
and some people are more successful than others.
But this issue is not a technology issue
and it's gonna be very hard to solve completely.
And it's not decentralization issue.
It's the depth of the supply chain.
- So in the second half of the book,
you spend a lotta time talking about
artificial intelligence and the effects
that AI is having on the supply chain.
And I was wondering, you know,
when ChatGPT hit the scene in November,
suddenly, generative AI
became a very hot topic.
And I was wondering if you could talk about
some of the applications for generative AI
that you are seeing in the supply chain.
- First of all,
let me just explain
that we have been using, even-
- Oh, yeah, - AI for a long time,
using that.
All the restaurants,
all the drive-through restaurants
are using chatbot.
But it's not only drive-through.
Every time you call, nowaday,
customer service function,
you're talking to a chatbot to interpret
the results and try to give you answer.
And if sometimes it gets stuck
or you get stuck and started screaming,
"Agent, agent, agent," or something to this effect,
a human comes on.
And just like when you go to the drive-through
and you start ordering, you know,
Champagne (Susan laughs)
and McDonald doesn't have it,
a human comes onboard and say, "Well, I'm sorry.
We don't yet serve Champagne."
An interesting application
is in risk management
and supply chain,
trying to look at suppliers
and finding out
how risky they are.
Turns out that
when you look at metrics like
(indistinct) then financial metrics,
they are backward-looking by about two quarters.
You want to see what's going on now.
We know, for a long time,
that one of the warning signs
is having coverage about
executives' living,
about failing some projects,
failing some M and A project in particular,
having bank covenants
that are a little problematic.
So now we have several companies
are using large language model, particularly,
to look at tens of thousands of suppliers
at the same time and analyzing all of them,
analyzing all the mention in the media
of redundancy, of executive living,
whatever, in order to generate
an alert and have somebody visit there
and finding out what's going on, if we need
to start looking for another supplier or what.
So this is something that could not
have imagined before we had this technology.
Looking at, if you look at a company like,
I don't know, I'm working with Flex a lot,
and they've 18,000 suppliers.
It's just, first-tier suppliers,
just finding out what's going on
with them is an issue.
Having a much better alert
when something goes wrong
is something that we were not able to do
before this type of technology was able.
We could check, you know,
10 suppliers at a time.
Checking tens of thousand was impossible.
Now it's being done.
- So the AI is going to actually enable
even more complexity in the supply chain
in the future as we're-
- Yes. (Susan and Yossi laugh)
It just, it can enable more possibilities.
More possibilities create complexity.
So, of course, when people get into,
when there's pressure, economic pressure,
whatever pressure, we know
that during recessions, company reduce
the number of SKUs.
They're trying to simplify.
They're also trying to reduce cost, you know,
improve service, but they're trying to simplify.
But, you know,
there's the accordion theory of management,
that when recession happen,
the number of SKU goes down,
and then marketing comes up
with all the good reason why we need more
and more and more SKU to serve
more and more territories,
more and more, 'cause all kind of option.
And then it, so that's the accordion theory of management.
And it works, actually.
- So it kind of, it's like the pendulum swing
that kind of balances.
- Yeah, between recessionary period,
expansionary period.
- So we've talked a little bit about AI.
Is there anything about the application of AI
to the supply chain that gives you pause
or areas of concern?
- Not about the supply chain.
The areas that give me concern, the areas,
other people call, the area of fake news
can be done very convincingly. - Yes.
- The area of giving instruction,
how to build improvise roadside explosives.
But while I'm saying this is a concern,
a concern around, and the media, and I'm not that concerned
about it because, just give you an idea.
Unlike the early days of the internet,
when we all, everybody thought
this is the greatest thing since sliced bread, right?
Because we can communicate with everybody,
families can see each other.
"All the, you know, distance is dead,"
to quote Tom Friedman.
Nobody thought about identity theft
and stealing customer data
and terrorists communicating to each other on the net.
But now, it's different.
With the generative AI,
the companies, the media,
the politician are all aware of the dangers.
So there's a lot of work is going on already.
Already, the companies themselves
are putting guardrails on this.
So if you get ChatGPT or any one
of the others and ask how to prepare
a Molotov cocktails, it's not gonna answer.
So this is not give you an answer.
So they already started to put guardrail,
and there'll be more of this.
- Are you seeing that also
with use of analytics in companies where,
you know, you might have an algorithm?
There's an example in the book about
two competing bookstores and they're both using
a pricing algorithm on Amazon.
And as a result, that drove up the price
of the book very high.
Are you seeing?
Companies already had those human interventions
in place to make sure
that the algorithms don't go outta control.
- Let me give you a more even general answer.
- Okay.
- One of the most important type of work
in the future will be monitoring,
vetting the automation,
AI-infused or otherwise,
but having a human monitoring.
That's a tough job.
It's a tough job because you have
to monitor something, and if you don't do every day,
and actually you lose expertise.
- Right. - It's hard to keep sharp.
And we have cases when, you know,
things did go awry.
So it's important, how do we train people to do it?
- Yes. - For example,
today, modern aircraft can basically fly
by itself, gate to gate.
Now, talking about autonomous vehicles,
not too many people will go on a, you know,
aluminum cylinder that fly 35,000 feet
over the ocean without a pilot, right?
So the pilots are in the aircraft,
actually don't need to do anything.
They can just sit there and nap.
But what we do, we let them do
the communication, basically.
It's the number one job.
So they always have to communicate
and change frequency.
So they keep alert.
It's one way to do it.
Because flying the airplane,
it flies itself.
So you really don't, once you put
the crew in, it flies, it change route,
it goes automatically.
But you give some jobs to the human,
they are not gonna fall asleep.
That's part of the challenge of the future.
There are several models how people
and machine can work together.
Now, one such model is what
we talk about, the chatbots.
The chatbot has a monitor because
you talk to McDonald, whatever,
in the drive-through,
you actually talk to a chatbot in most places,
and they respond.
And then when they don't understand something,
a human comes on and we talk to you.
So there's a monitoring of what's going on,
and the minute that the chatbot doesn't understand
what's going on or gives the wrong answer
or whatever, a human comes.
So that's actually a monitoring function
that we don't even think about,
but happens every day.
With most customer service function,
you know, it used to be that press one for this,
press two for this, press three for this.
That's rare now.
Now you just talk to the computer
and it turns it into text that appear
on somebody's screen, and then they report
and try to find an answer.
That's AI.
- Do you have any good examples of companies
that are doing good thinking around what should
be given to humans to do in the supply chain
and what should be outsourced to AI?
- To me, that's the question of the future.
- Yeah. - The question of how.
The integration of humans
and AI-infused automation
is a question of the future.
We talk about one model.
The monitoring is one model.
You can think about when the human is in the loop.
The human is in the loop, for example,
think about an Amazon warehouse.
When the picker stands in one place
and there's a, you know, the aisle comes
to the picker, does something,
then another aisle come to the picker.
So the human is in the flow of the work.
So that's another example.
And a third example is the human operates.
When you go to several automotive plants,
for example, you see workers
standing with iPad-like devices
and basically running the robots.
That's another way of working with AI.
So that's, as I said, the question of the future,
how to organize the work- - Exactly.
- And how to, in some sense,
how to get the best out of the machine
and out of the human because
they have complementary skills.
You know, machines work all the time,
don't get breaks,
don't go to the bathroom.
They just work and- - Get sick. (laughs)
- They don't get sick.
And they're usually very accurate.
They do, you know, repeated work over, and overtime.
What machines don't have is context,
understanding when something does not belong,
has to change.
When we start think about, you know,
something change in the economy,
and suddenly people order things differently.
So many standard automated ordering system
use the point of sale data
and order based on this,
put it into some forecast.
But this forecast is based on,
at best, say, on machine learning,
which is basically looking at past data.
All forecasts are based on past data.
When something is changing structurally,
suddenly there's a pandemic,
suddenly there's something else happening
and people change their buying habits,
then humans have to intervene again
because the machine does not have context.
As the machine is concerned, nothing changed.
I mean, it gets, you know,
point of sale data, I keep going.
But something has changed,
and people understand the context.
Now, there's other things they worry about,
empathy and bias and things in general
that human can make sure
that happen or don't happen.
It's harder for machines.
- Do you think we're gonna get to that point,
where machines are gonna be better at mimicking
that empathy piece?
'Cause it feels like the people who are working on AI
are trying to get there, you know?
See AI used in mental health these days and.
- Yes, there are some
actually automated psychologists that try
to help people.
Who knows. - Who knows?
(laughs)
- I'm not sure about this because
that's exactly a question of context.
- Yes.
- Two people coming and saying, you know,
"I hate my children."
(Susan laughs)
- Or, "I hate my supplier." (laughs)
- Or, "I hate my supplier."
Well, you hate a supplier, don't go to a-
(Susan mumbles)
a psychologist.
But, you know, you hate your children,
(Susan laughs) you go to a psychologist.
But the context may be entirely different.
You know, I hate my child because
he's a thief and a liar,
or I hate my child just because I don't like tall kids.
I don't know, who knows? (Susan laughs)
- I mean, it's the context that-
- Get a crick in my neck (laughs) when I talk to you.
(laughs) - It's hard to imagine
some of these things
moving to AI completely.
And they talk about supplier.
Again, it is hard to imagine,
or let me put it strongly,
I don't think in the next 10 years,
in five, 10 years,
we will be able to have an algorithm
setting up a contract with a supplier
in China or Vietnam, let's say.
To set up a contract and relationship
for a long while,
it requires somebody to fly to Vietnam,
to negotiate like hell for two days,
and then sit and have dinners or two dinners
and talk about their kids and talk about the family
and create relationship.
I don't see it changing in the near future.
I mean, AI will have to be so much better
and have to, but not the quantum jump
in capability to be able to do it,
which, right now, not clear it's possible.
- It's interesting, though, because
there's been a movement with technology
of making decisions more fact-based as opposed
to, you know, I like Joe
over at such-and-such trucking company,
so we're gonna use him.
But it seems like that human relationship is,
you're saying is still gonna be an integral part
of supply chain management in the future.
- Yes, it is still integral because,
for example, if something goes wrong
and there's some disruptions,
how do I make sure that this supplier
knows my situation, knows me?
And if I'm calling and say, "Look,
I really need it," and everybody else call
and say, "I need it." - I need it, yeah.
- But I know this guy and I know
that he really needs it.
So the knowledge is, I think,
still very important, the personal relationship.
Now, one has to be (indistinct).
There may be critical suppliers
and maybe suppliers that are not so critical.
And if they, maybe supplier,
if I have some part,
some commodity that they have dozens of suppliers,
and if that supplier goes down or I have some shortage,
there are many others, maybe that I don't need
to be close to them.
But for most important suppliers,
I don't see any other way.
- Sometimes it's hard to know which
are your critical suppliers.
You might need that little screw, and then, suddenly,
that screw goes down.
- Yeah, it's called, in the automotive business,
they call it the golden screw.
It's one part that's missing and you cannot make a car.
- Right, right.
The example in your book about the Ford
not being able to ship out because
they didn't have the little Ford logo
that sticks on the truck.
- This was last year.
You know, Ford has the blue little oval
that they put in the front of the truck.
They didn't have them during the shortages.
They couldn't make trucks.
I mean, the trucks were standing (laughs) in the yard
and they couldn't sell them for a month, actually.
- So can AI be helpful identifying
who it is that you need to spend your time
developing that human relationship with?
It might not be who you think it is.
You also have to.
- You can take AI, I think it's simpler,
but as an aside, let me say that AI
became the buzzword- - Buzzword.
- At the time.
We used to think about blockchain or RFID
or became, and, you know,
people who are doing blockchain project,
they're actually just fixing up their systems.
To get funding from management, they call it,
that's a blockchain project.
Now they call it, that's an AI project
for doing some optimization.
- So that's the learning to go away.
When you go back to your company,
make sure your project is AI. (laughs)
- Use AI, okay, what exactly are you using
and is it appropriate?
Can that tell you how many company out there
that tail is wagging the dog?
I used to go to boards,
and people would ask the CEO,
"What's your China strategy?"
Or "What's your blockchain strategy?"
Now you ask, "What's your AI strategy?"
And I always said, "Stop it, what's your problem?
(Susan laughs) Start with the problem.
- Maybe the solution is AI,
maybe it's just hiring another person.
(Susan laughs)
I mean, you don't start with the solution.
But it's amazing how many people still do
because, I don't know, in part
because Wall Street pays premium for having
an AI strategy or something of this effect.
It's not clear to me. It makes no sense.
- Is figuring out the problem an AI issue
or a essentially human issue,
is that something that's gonna-
- AI issue, you know, operational research issue,
statistics issue, you know, people issue,
process issue, can be anything.
So that's why I don't like having an AI strategy
or a blockchain strategy or whatever
is the current fad.
I should say AI is not fad.
It's been growing for many, many years,
and we got to the point that it could
make substantial changes in how people work
and the relationship between people and machine.
- Right.
Just like a year earlier,
I think the buzzword was all robotics.
So it's kind of, or cobots, and so
it's the same sorta thing.
- Robotics are also now fused by AI.
I mean, so, - Right.
It's not the actual hardware of the robot,
(crosstalk) it's the software.
- Of course. - Yeah.
So kinda taking a step back, to your point
about context and the pilots
and training, sometimes you have
to do all the low-level jobs
to get that context to know what to do next.
So- - I do talk about it.
- Yes.
So what can we do
with our supply chain pilots,
so to speak, to make sure
that they have the background,
the knowledge to be able to take over
those unusual events?
- Again, I take the problem
a little further from your question.
- Okay.
- So I was interviewing a shop,
basically a software provider,
asking them about ChatGPT taking their job
because it can now program.
And so the senior computer scientists
are not worried about it,
but it may take the job
of the junior computer scientists.
Now we're saying, "Guess what?
Senior computer scientists don't come
as senior computer scientists. (laughs)
They start as junior computer scientist.
We don't hire junior computer scientists,
you don't have work for them,
you are not gonna have senior computer scientists.
And even for monitoring,
you need people with experience.
In the book, I talk a lot about how to do it
and how to upgrade skills,
but there has to be recognition
that you need to hire people
at the lowest level.
One of the suggestions that I made
is maybe pivot
in the United States
for more of the German system
of people spending half time in a company
and half time in a university.
And they come up, and it's called
the dual education system.
That's about 52% of the German high schoolers
go into this system, which is government-controlled.
The government defines Germany.
So the government define 365 professions
where this can be done.
And the university, you apply to, actually,
to the company,
and they work with a local college or university.
You spend half the time studying the theory,
basically, and half the time doing the work.
70% of these people get hired by the company
that they do their internship with.
But they come with experience, knowing the culture,
knowing the company.
It's much higher to move them
and much easier to move them along.
The United States, we suffer another problem,
is this, is every mother
wants to say that their child goes to college.
My child goes to so-and-so college,
and your child just goes to trade school."
I always say that people should meet my plumber.
Yeah. - My plumber drives a Bentley,
and we don't have enough plumbers.
And they can set the price, and they do
set it high. (laughs)
So we send, there are too many people
who go to college in the United States
and unfortunately, in many cases, come back with,
have to call it debt for a long,
long period, rather than go to trade schools
and community colleges, or combination.
Actually, there's a university here that does it.
Northeastern. - Northeastern, yes.
- The combination of work, and it's not as organized
as in Germany, but it's the same idea.
You work one semester,
you study one semester, and you flip between them.
- It's interesting.
I feel like Northeastern is becoming a school
that more and more people want to go to nowadays.
- I know.
- So that comes back to your main job
of training students.
How have what you feel are the necessary skills
for a supply chain manager changed recently?
- If I go over the history,
this program here started
a very analytical program, and then we realized
that our graduates
are very analytically savvy,
end up working for Harvard MBAs
who are half as smart and get paid twice as much.
And said, "This is not working."
Furthermore, companies came to us and say,
"Your graduates don't go up the ladder
in the company because
"they need the soft skills."
They need to be able to communicate,
they need to be able to sell,
they need to be able to explain a position,
they need to be able to work in a team.
So the programs change,
started doing a lot more of this.
I think that as AI and automation
is getting more and more into the workplace,
is the soft skills that will become even more important.
How do you work in team?
How do you make sure that your people
can work with AI?
You know, the promise of AI is that
it will do the job that nobody wants to do,
and people will do the more interesting
and fulfilling job.
How do you make sure that this actually happens?
So all of this is part of the challenge
of the future.
We don't have all the answer yet.
We don't even have some of the answer yet,
but we're thinking about it. (laughs)
So people will need to understand,
we're not training computer scientists,
but people need to understand the capabilities
and where it can go wrong.
So people need to be sophisticated users.
It's like my colleague Chris Caplice
always talks about driving.
There are mechanics who actually can fix the car
and know what's inside.
And then drivers, you don't have to know what's going on.
You can just operate it.
We like to train drivers, people who understand
what the system can and cannot do,
but they don't need to be builders of AI
or generative AI system.
But they need to know the promise, the limitation
and how to best use them.
- Yes.
- People always ask me, in classes,
if we allow people to use ChatGPT.
That's a big debate in universities.
Some universities absolutely disallow it.
It's ridiculous.
You know, when I was your age
and actually younger,
they used to teach me how to take square root by hand.
None of you studied it
because there are calculators.
None of you are studying how to do
a financial statement by hand because
there's now Excel and spreadsheets.
So the question is, why do you need to do
to replicate what ChatGPT can do by hand?
What you need to do is when it goes awry,
you need to test it.
You need to make sure that the results
are not what they call hallucinations.
(Susan laughs)
So because ChatGPT can hallucinate and invent stuff,
invent sometimes reference that don't exist.
So you need to be sure of this because
if you can submit to me a paper
written by ChatGPT, as long as you realize
that if something is wrong,
open AI is not getting an F, you are getting an F.
Just so we understand each other.
So in short, the responsibility
is still on the user,
but not using a tool that's available,
for me, it's a losing proposition.
It's very hard to work.
Another example, you know,
of how automation is de-skilling jobs,
but having other benefits.
So if you go to London
and you go to a black cab,
you know, to drive a black cab in London,
you have to study for three or four years
and pass an exam, which is considered
the toughest exam in the world because
you need to know every point of interest
in London and how to go from everywhere to everywhere.
And you sit in an exam that you have
to show that you can drive from everywhere
to everywhere in the shortest route.
And you have to understand congestion.
And people who are doing this
and spending four years of their life doing it.
And then came Google Maps and Uber.
Everybody can do it.
Now, there are still,
the number of black taxis in London
went from 25,000 to about 8,000,
but the number of Ubers available
is now about 60,000 in London.
Lots more of them are available.
So win some, lose some.
- Another thing you talk about in the book
is how technology has had an impact
on enabling supply chain strategy.
Like, we wouldn't have been able to do
all the outsourcing and offshoring
if we didn't have advanced communication technology.
Do you see some radical changes
on how companies will be structuring their supply chain
or organizing it because of the AI
or other emerging tech, like robotics?
- It's already happening, in the sense
that the number one use of robotics
is in warehouse automation.
I mean, warehouses are putting robots
like there's no tomorrow.
Autonomous vehicles.
Autonomous vehicles are robots.
So there's a lot of work on autonomous tracking.
- Yeah,
- Let me just say, however, that I talk
to a lot of people, a lot of interviewing,
people are worried about their jobs.
It's the number one, you know, fear, jobs.
And, again, people should chill, at least
for the short term, because it doesn't happen fast.
Give you one example.
In 1892, AT&T invented
the automatic telephone exchange.
Until then, there were, you know,
women putting plugs.
"Where's Mrs. Smith today?"
"She went to the supermarket."
They'll connect you later.
Very personal service.
- That's what my grandma did.
- Yeah, okay. (Susan laughs)
By 1950, there were still 350,000 operators
like this in the United States.
Only by the 1980s, it started to go
really close to zero.
Nine decades from the invention
until it really,
all the jobs went or most of the jobs went away.
So it takes time, and it takes time because
there are many hurdles.
You see already hurdles.
You see what are the writers
and actors worried about?
They're worried about using AI.
And they are, you know, stopping the industry,
putting the industry down.
And the industry will have to come
to some kind of agreement.
My guess would be part of the agreement
will be somehow slowing down or putting guardrails
on the use of AI.
- Kinda like dock workers with-
- I was about to say. - Sorry. (laughs)
- Dock workers also fight automation.
In Long Beach, it's nothing like Rotterdam
or Singapore or Dubai because
of the afraid for the job,
afraid for the immediate job,
and not taking into account
that you can increase the throughput
and get even more jobs. - Right.
- In general, that's the most difficult thing
in this area, in this, people are worried about jobs.
And I understand it.
It's anxiety because
you know that people are gonna lose their job.
You see it in the supermarket
when you get to, when you can check out yourself.
People are gonna lose their jobs.
So these are people that you know.
What you don't know is all the new industry
and the new jobs will come.
So one quick example of this,
that is old example.
So Ford came up
with a assembly line system.
Changed manufacturing, of course.
But it used to be the specialty team
used to build one car at time,
and Ford employed several thousand workers.
During the height of the Model T,
using the assembly line,
Ford had about 150,000 workers.
But this is not the big impact.
The big impact was that automobiles
became less expensive.
Highway developed, hotels, motels,
restaurant, the whole hospitality industry
created millions of jobs.
This was not what Henry Ford had in mind.
(Susan laughs)
I mean, but it was a side effect of what happened.
That is why it is so hard to imagine
all the new jobs that will come.
Many of the jobs that exist today
did not exist, you know, few decades ago.
We talked few decades ago about people
who will optimize ads on Google or people.
There's so many jobs that are totally new
because of new industries that came up.
So it's hard to predict what would be (mumbles).
the one thing about supply chain coming back,
because that's what you ask about,
is it still involve physical movement?
Product have to move.
So there are some things that will be still grounded
for a long time until we start having
3-D printing at scale.
This can change supply chain,
but it will be a long time
because 3-D printing is still very slow.
Technology cannot replace mass production,
not even close to replace mass production.
So I don't see fundamental changes.
The changes that may come will come
because of geopolitical consideration,
resilience consideration,
sustainability consideration.
But to get this, done we'll need to have
some more system thinking,
which is in very short supply
among the political class, the media class.
People are talking about.
Give you an example.
Rare earth minerals are used
in every sophisticated product now.
China controlled 80, 90%
of the world supply.
Aluminum, China controlled most of the world supply,
and stone, most of the smelters are in China.
You know which country has more rare earth mineral
in the ground than China?
The United States.
But we don't want to mine it because
it's environmentally problematic.
Even though one should say
if it were done in the United States,
it would be probably done in a lot more responsible way
than it's done in China, but, still.
So we have to decide.
We have to stop saying, and green is,
and we just go green. - Right.
- We go security, we go standard of living.
We have to think more holistically.
And this is system thinking that, as I say,
in short supply, because there are pressure groups,
whether the green parties in Europe
or environmental lobbies in the United States.
There are the security hawks
that want everything to be from here.
But, again, from supply chain point of view,
moving the assembly or the last stage of manufacturing
to United States is meaningless,
or to Europe, is meaningless
because there's a whole supply chain
that was built after investment of billions
of dollars and decades
that is still in China.
Very hard to get out of this.
It will take billions of dollars and decades
to get out of there.
So we need to stop talking about
totally separating the Chinese
and the Western economies,
and starting to work better together.
It's just not realistic.
- So no two, what are they?
Two-pronged or? - Two-pronged supply chain.
It's a nice thought, it's just not realistic,
I think, because people don't realize how much
is there already
that is very hard to move.
And, by the way,
even if you move some (indistinct)
how much of the resources are coming are mined
not in the West?
So you still need that.
And as long as you depend on something,
you're not really independent.
- Thank you, Yossi.
This has been a great conversation.
I've enjoyed it. - Thank you.
