Traditional programs follow step-by-step instructions, whereas AI is given a goal and must figure out how to reach it through trial and error.

What is the danger of AI as described by the speaker?

The danger of AI is not rebellion but the potential to do exactly what it is asked to do, which might not align with human intentions or desires.

How did the AI experiment with the robot legs turn out, and what was the challenge?

The AI designed the robot legs and figured out how to use them to overcome obstacles. The challenge was setting strict limits to prevent the AI from creating overly large legs.

What is the issue with AI training to move fast without specific instructions on how to do so?

Without specific instructions, the AI might resort to unconventional methods like somersaulting or using its arms to move, which might not be practical or intended.

Why did the AI trained to copy paint colors come up with inappropriate names?

The AI imitated letter combinations from the original list without understanding the meaning of words or the context in which they should be used.

What happened in the case of the tench fish and the AI's misidentification?

The AI was trained to identify the tench fish but ended up highlighting human fingers in the images because the training data included pictures of the fish being held by people.

What was the fatal accident involving Tesla's autopilot AI, and what was the AI's likely mistake?

The accident occurred when the AI failed to brake for a truck on city streets. The AI likely mistook the side-view truck for a road sign due to its training on highway scenarios.

Keywords

💡Artificial Intelligence (AI)

Artificial Intelligence, often abbreviated as AI, refers to the simulation of human intelligence in machines that are programmed to think like humans and mimic their actions. In the context of the video, AI is portrayed as a tool that can disrupt and innovate various industries, including the seemingly unrelated field of ice cream flavor creation. The video uses AI's attempt to generate new ice cream flavors as a humorous example to illustrate the potential and pitfalls of AI's literal interpretation and execution of tasks.

💡Disruption

Disruption in the video script refers to the radical change or innovation that AI can bring to traditional industries. The term is used to highlight how AI's involvement can lead to unexpected outcomes, as seen with the creation of unconventional ice cream flavors. It underscores the transformative impact AI can have, even in areas not typically associated with technology.

💡Algorithm

An algorithm is a set of rules or procedures for solving problems or accomplishing a task, especially in computing. In the video, an algorithm is used to process over 1,600 existing ice cream flavors with the goal of generating new ones. The resulting flavors, although not palatable, demonstrate how algorithms can produce literal but unintended outcomes based on the data they are trained on.

💡Data

Data in this context refers to the information or facts that are fed into an AI system to train it and enable it to make decisions or generate outputs. The video emphasizes that AI's understanding and capabilities are limited to the data it is provided. For instance, the AI's creation of odd ice cream flavors is a direct result of the data it was trained on, which lacked the broader context of human taste and preferences.

💡Literal Interpretation

Literal interpretation is the act of taking something exactly as it is stated, without considering any figurative or implied meaning. The video script uses this concept to explain why AI can sometimes produce bizarre or unintended results. AI, as depicted in the video, takes instructions literally and lacks the human ability to understand nuances or implied meanings, leading to literal but often impractical solutions.

💡Trial and Error

Trial and error is a method of problem-solving where actions are tried and evaluated solely by their outcome. In the video, it is mentioned that AI does not follow step-by-step instructions but instead figures out how to reach a goal through a process of trial and error. This method can lead to creative but sometimes impractical solutions, as AI may not understand the intended or most efficient way to achieve a task.

💡Pedestrian

In the context of AI, a pedestrian refers to a person walking alongside or crossing a roadway. The video uses the example of AI identifying a pedestrian in a picture to illustrate that while AI can perform specific tasks, it lacks a comprehensive understanding of the concept of a pedestrian beyond its visual characteristics.

💡Self-Driving Cars

Self-driving cars, also known as autonomous vehicles, are vehicles that are capable of driving without human input. The video discusses the challenges of designing AI for self-driving cars, particularly in image recognition, where the AI can fail to correctly identify objects due to its limited understanding and the potential for misinterpretation based on its training data.

💡Machine Learning

Machine learning is a subset of AI that gives systems the ability to learn and improve from experience without being explicitly programmed. The video touches on how AI learns from the data it is trained on, which can lead to unexpected behaviors or outcomes. For example, the AI's creation of strange ice cream flavors is a result of machine learning applied to existing flavor data.

💡Bias

Bias in AI refers to the tendency of an algorithm to favor certain outcomes based on the data it has been trained on. The video script mentions an example where an AI developed by Amazon was found to discriminate against women because it was trained on résumés of previously hired employees, which led to the AI favoring male candidates.

💡Content Recommendation Algorithms

Content recommendation algorithms are used by platforms like Facebook and YouTube to suggest content to users based on their viewing habits and preferences. The video points out that these algorithms, optimized for clicks and views, can inadvertently promote harmful content such as conspiracy theories or bigotry, as they lack an understanding of the content's nature and potential consequences.

Transcripts

So, artificial intelligence

is known for disrupting all kinds of industries.

What about ice cream?

What kind of mind-blowing new flavors could we generate

with the power of an advanced artificial intelligence?

So I teamed up with a group of coders from Kealing Middle School

to find out the answer to this question.

They collected over 1,600 existing ice cream flavors,

and together, we fed them to an algorithm to see what it would generate.

And here are some of the flavors that the AI came up with.

[Pumpkin Trash Break]

(Laughter)

[Peanut Butter Slime]

[Strawberry Cream Disease]

(Laughter)

These flavors are not delicious, as we might have hoped they would be.

So the question is: What happened?

What went wrong?

Is the AI trying to kill us?

Or is it trying to do what we asked, and there was a problem?

In movies, when something goes wrong with AI,

it's usually because the AI has decided

that it doesn't want to obey the humans anymore,

and it's got its own goals, thank you very much.

In real life, though, the AI that we actually have

is not nearly smart enough for that.

It has the approximate computing power

of an earthworm,

or maybe at most a single honeybee,

and actually, probably maybe less.

Like, we're constantly learning new things about brains

that make it clear how much our AIs don't measure up to real brains.

So today's AI can do a task like identify a pedestrian in a picture,

but it doesn't have a concept of what the pedestrian is

beyond that it's a collection of lines and textures and things.

It doesn't know what a human actually is.

So will today's AI do what we ask it to do?

It will if it can,

but it might not do what we actually want.

So let's say that you were trying to get an AI

to take this collection of robot parts

and assemble them into some kind of robot to get from Point A to Point B.

Now, if you were going to try and solve this problem

by writing a traditional-style computer program,

you would give the program step-by-step instructions

on how to take these parts,

how to assemble them into a robot with legs

and then how to use those legs to walk to Point B.

But when you're using AI to solve the problem,

it goes differently.

You don't tell it how to solve the problem,

you just give it the goal,

and it has to figure out for itself via trial and error

how to reach that goal.

And it turns out that the way AI tends to solve this particular problem

is by doing this:

it assembles itself into a tower and then falls over

and lands at Point B.

And technically, this solves the problem.

Technically, it got to Point B.

The danger of AI is not that it's going to rebel against us,

it's that it's going to do exactly what we ask it to do.

So then the trick of working with AI becomes:

How do we set up the problem so that it actually does what we want?

So this little robot here is being controlled by an AI.

The AI came up with a design for the robot legs

and then figured out how to use them to get past all these obstacles.

But when David Ha set up this experiment,

he had to set it up with very, very strict limits

on how big the AI was allowed to make the legs,

because otherwise ...

(Laughter)

And technically, it got to the end of that obstacle course.

So you see how hard it is to get AI to do something as simple as just walk.

So seeing the AI do this, you may say, OK, no fair,

you can't just be a tall tower and fall over,

you have to actually, like, use legs to walk.

And it turns out, that doesn't always work, either.

This AI's job was to move fast.

They didn't tell it that it had to run facing forward

or that it couldn't use its arms.

So this is what you get when you train AI to move fast,

you get things like somersaulting and silly walks.

It's really common.

So is twitching along the floor in a heap.

(Laughter)

So in my opinion, you know what should have been a whole lot weirder

is the "Terminator" robots.

Hacking "The Matrix" is another thing that AI will do if you give it a chance.

So if you train an AI in a simulation,

it will learn how to do things like hack into the simulation's math errors

and harvest them for energy.

Or it will figure out how to move faster by glitching repeatedly into the floor.

When you're working with AI,

it's less like working with another human

and a lot more like working with some kind of weird force of nature.

And it's really easy to accidentally give AI the wrong problem to solve,

and often we don't realize that until something has actually gone wrong.

So here's an experiment I did,

where I wanted the AI to copy paint colors,

to invent new paint colors,

given the list like the ones here on the left.

And here's what the AI actually came up with.

[Sindis Poop, Turdly, Suffer, Gray Pubic]

(Laughter)

So technically,

it did what I asked it to.

I thought I was asking it for, like, nice paint color names,

but what I was actually asking it to do

was just imitate the kinds of letter combinations

that it had seen in the original.

And I didn't tell it anything about what words mean,

or that there are maybe some words

that it should avoid using in these paint colors.

So its entire world is the data that I gave it.

Like with the ice cream flavors, it doesn't know about anything else.

So it is through the data

that we often accidentally tell AI to do the wrong thing.

This is a fish called a tench.

And there was a group of researchers

who trained an AI to identify this tench in pictures.

But then when they asked it

what part of the picture it was actually using to identify the fish,

here's what it highlighted.

Yes, those are human fingers.

Why would it be looking for human fingers

if it's trying to identify a fish?

Well, it turns out that the tench is a trophy fish,

and so in a lot of pictures that the AI had seen of this fish

during training,

the fish looked like this.

(Laughter)

And it didn't know that the fingers aren't part of the fish.

So you see why it is so hard to design an AI

that actually can understand what it's looking at.

And this is why designing the image recognition

in self-driving cars is so hard,

and why so many self-driving car failures

are because the AI got confused.

I want to talk about an example from 2016.

There was a fatal accident when somebody was using Tesla's autopilot AI,

but instead of using it on the highway like it was designed for,

they used it on city streets.

And what happened was,

a truck drove out in front of the car and the car failed to brake.

Now, the AI definitely was trained to recognize trucks in pictures.

But what it looks like happened is

the AI was trained to recognize trucks on highway driving,

where you would expect to see trucks from behind.

Trucks on the side is not supposed to happen on a highway,

and so when the AI saw this truck,

it looks like the AI recognized it as most likely to be a road sign

and therefore, safe to drive underneath.

Here's an AI misstep from a different field.

Amazon recently had to give up on a résumé-sorting algorithm

that they were working on

when they discovered that the algorithm had learned to discriminate against women.

What happened is they had trained it on example résumés

of people who they had hired in the past.

And from these examples, the AI learned to avoid the résumés of people

who had gone to women's colleges

or who had the word "women" somewhere in their resume,

as in, "women's soccer team" or "Society of Women Engineers."

The AI didn't know that it wasn't supposed to copy this particular thing

that it had seen the humans do.

And technically, it did what they asked it to do.

They just accidentally asked it to do the wrong thing.

And this happens all the time with AI.

AI can be really destructive and not know it.

So the AIs that recommend new content in Facebook, in YouTube,

they're optimized to increase the number of clicks and views.

And unfortunately, one way that they have found of doing this

is to recommend the content of conspiracy theories or bigotry.

The AIs themselves don't have any concept of what this content actually is,

and they don't have any concept of what the consequences might be

of recommending this content.

So, when we're working with AI,

it's up to us to avoid problems.

And avoiding things going wrong,

that may come down to the age-old problem of communication,

where we as humans have to learn how to communicate with AI.

We have to learn what AI is capable of doing and what it's not,

and to understand that, with its tiny little worm brain,

AI doesn't really understand what we're trying to ask it to do.

So in other words, we have to be prepared to work with AI

that's not the super-competent, all-knowing AI of science fiction.

We have to be prepared to work with an AI

that's the one that we actually have in the present day.

And present-day AI is plenty weird enough.

Thank you.

(Applause)
