Q & A
What was the special message Carl Sagan was asked to write in 1972?
-The special message Carl Sagan was asked to write was intended to be sent to outer space on the 'Pioneer 10' probe, which was to leave the solar system. The message had to be easily understood by any form of alien intelligence.
What principles did Carl Sagan and his colleagues decide to use in drafting the message for the 'Pioneer 10' probe?
-They decided to use the hydrogen molecule, the position of the stars, and a set of theoretical mathematical principles, assuming that any form of intelligence in the universe would have evolved within the same physical and mathematical laws as we know them today.
Why did Sagan later prepare a message using the principles of prime numbers for alien intelligence?
-Sagan prepared a message using the principles of prime numbers because he believed that such a fundamental mathematical concept could be a universal language, or 'lingua franca,' that any intelligent being could understand.
What does the speaker imply about the effectiveness of Sagan's messages in communicating with alien intelligence?
-The speaker implies that Sagan's messages might not have been effective because they did not receive any feedback, suggesting that the messages may not have been comprehensible to alien intelligence, or that the assumptions about shared understanding of physical laws and mathematics were incorrect.
What was the mistake Carl Sagan made according to the speaker?
-The mistake Carl Sagan made, according to the speaker, was that he had difficulty imagining something truly alien and conceived a message that was too human-centric, essentially looking for another version of himself rather than a truly different form of intelligence.
How does the speaker define an intelligent agent?
-The speaker defines an intelligent agent as an entity with goals, capable of learning from mistakes, adjusting, and thinking. This includes not just humans and other living beings but also machines that can understand, learn, and make decisions based on data and statistical relationships.
What are the three shortcuts taken to create today's intelligent machines?
-The three shortcuts taken to create today's intelligent machines are: 1) the use of statistics to replace deep theories, 2) leveraging preexisting data found 'in nature' or on the web, and 3) constant user observation to build mathematical models of user preferences.
Why is it important to understand the nature of today's intelligent machines?
-It is important to understand the nature of today's intelligent machines because they are at the heart of the global infrastructure, making decisions that impact our lives. Understanding them helps us draft regulations, solve real problems, and coexist effectively with these machines.
What are some of the concerns raised about the use of algorithms in today's society?
-Some concerns raised about the use of algorithms include their potential to make suspicious and debatable decisions, issues of neutrality and honesty, the possibility of racist algorithms, the spread of fake news, and the problem of behavioral addiction to machine-recommended content.
Why is it crucial to regulate and understand the algorithms that power the web?
-It is crucial to regulate and understand these algorithms because they have been delegated with important decisions that affect our lives. Proper regulation and understanding can prevent misuse, ensure fairness, and protect vulnerable individuals from harm.
What does the speaker suggest is the key to successfully coexisting with intelligent machines?
-The speaker suggests that the key to successfully coexisting with intelligent machines is understanding that they possess a different type of intelligence than humans. Accepting and respecting this difference will allow us to adjust our expectations, regulations, and educational approaches accordingly.
How does the speaker relate the understanding of intelligence in machines to the historical realization that humans are not the center of the universe?
-The speaker relates the understanding of intelligence in machines to the historical realization that humans are not the center of the universe by drawing a parallel between the two Copernican shifts in perspective. Just as we had to accept our place in the cosmos, we must also accept that our form of intelligence is not the only one and that machines can be intelligent in their own unique way.

What does being intelligent mean?
This question suddenly became relevant,
in 1972,
to the American astronomer Carl Sagan,
when he was asked to write a very special message.
It was a message to be sent to outer space
on the "Pioneer 10" probe that was to leave the solar system.
The message had to be easily understood by any form of alien intelligence.
Carl Sagan consulted his physics and mathematics colleagues,
and they all decided to draft a message
that would use the hydrogen molecule, the position of the stars,
and a set of theoretical mathematical principles.
Their idea was that any form of intelligence in the universe
would have to evolve
within the same physical, math laws as we know them today,
and should therefore be in a position to understand them.
This was the "lingua franca" they intended to use.
Some years later,
Sagan even prepared a message
to be sent to alien intelligence via radio telescopes
featuring a series of bits
using the principles of prime numbers.
Well, I showed his messages
to my cat -
who is an intelligent being, understands everything,
can deceive both the mice and me whenever it wants to -
along with the other message,
without getting any feedback whatsoever.
This leads us to believe
that perhaps the aliens received Sagan's message, too.
The question is: where did Sagan go wrong?
The answer is not so difficult:
he had difficulty imagining something truly alien
because it's not easy to conceive something so different from us.
Indeed, his message would have been incomprehensible
even on this planet, even to humans,
Leonardo da Vinci, 500 years ago,
couldn't know the hydrogen molecule.
And even today, on this planet,
many people are not interested in prime numbers.
What he was looking for was not intelligence,
but rather another version of himself.
And it's a mistake we always make, we've often made throughout history,
and he was no exception.
It is a lesson for us to learn, one of the limitations we have.
And so, how can we think of an intelligent agent?
Well, imagine an entity, in this case you can see a bee,
with targets to reach.
The bee wants sugar, in the form of nectar;
it has to make decisions, maybe mistakes at first -
but learns eventually.
But there's also a plant that wants to pollinate other plants,
and to do so it must manipulate the bee.
So it does the same.
Agents with goals,
capable of learning from mistakes, adjusting and thinking
are intelligent agents.
Intelligence isn't a "signature" of humans.
For sure,human beings are not the only intelligent ones:
there was intelligence on this planet before us.
Living beings are not the only ones, either.
Machines can be intelligent.
YouTube is able to understand what to suggest,
when and to which user
in order to get us to click.
If it makes mistakes, it learns.
How were we able to do this?
It is important to understand how we did this version of smart machines
because we have to live with them, draft regulations;
and all of this makes no sense
if we try to solve problems that do not exist,
and regulate machines that do not exist.
Those existing today
have been made by us more or less in the same way,
by taking shortcuts.
The first shortcut is the use of statistics.
After many decades of trying to do what Carl Sagan did,
and instill in machines
a type of intelligence similar to ours - human, mathematical -
the kind of intelligence one typically finds in a scientist -
we found out, that method wasn't successful.
Today, if I Google "Cernobbio",
without even typing the whole sentence, based on statistical criteria alone,
it understands what I want to say, what information I might need,
and tries to predict my actions and my needs.
Statistics can often replace
the deepest theories.
This, in turn,
triggers a need for data, lots of data,
in which to find these statistical relationships.
This is the second shortcut we took:
instead of producing data ourselves, by paying,
we take it from where we can find it - "in nature", as we use to say.
And data already existing in nature is to be found on the web,
where much can be learned about both Lake Como
and "The Betrothed", and many other sources,
with different degrees of accuracy and reliability.
And then?
And then the machine has to understand what the user wants,
which is no easy task for a machine.
So we took a third shortcut:
we decided to constantly monitor the user,
assuming that each click signals his or her preferences,
and eventually built a mathematical model of each user.
Here they are:
preexisting data in nature, statistical relationships
and constant user observation.
These are the three ingredients we use in todays' recipes
to create the intelligent machines we use all the time:
it goes for Instagram, Facebook, Amazon and Tik Tok.
And also for ChatGPT.
We don't fully understand what they know,
precisely because they're made with a statistical approach.
But we've placed them at the heart
of the global infrastructure that makes the world go round:
the web.
We have delegated important decisions
to these machines,
which have an impact on all of our lives.
What can go wrong?
Well, for starters, we notice
that these algorithms sometimes make suspicious and debatable decisions,
which make us question their neutrality and their honesty.
Some talk about racist algorithms,
some want to use them to win electoral support.
Some notice that fake news circulates because the algorithm recommends them.
And then there's the issue of behavioral addiction:
there are people who can't stop
using content recommended by a machine.
So how can we trust them?
How can we leave a child in front of YouTube, TikTok,
or a vulnerable adult?
Are there any side effects?
How can we make sure nobody will get hurt?
Fortunately, for a few years now,
we have been looking into this issue,
and not only scientists, everybody.
And today, parliaments across the globe
are openly talking about artificial intelligence.
Two weeks ago, Heads of State met in Bletchley Park
to discuss A.I.
This is something I never dreamed of as a student.
I've been working on these issues for 28 years now,
and I never thought I'd see the world's prime ministers
discussing intelligent algorithms.
MEPs have come a long way, the law is almost ready.
Maybe, this time we won't make the mistake we made with the environment;
perhaps, we started off in time
and will have enough time.
What matters is, we cannot pull the plug,
not only because it is technically impossible, today,
to pull the plug and live without these devices.
The entire web works thanks to smart algorithms.
There's no point in having a library without a catalogue,
and we can't use YouTube or the web
without an algorithm finding content for us.
And besides, it wouldn't be fair.
There are many people who waited for decades
for their chance to access affordable education
and affordable health care:
now it's their time.
These methods are going to give so much to everyone.
It would be crazy to pull the plug.
But we have to live with them, regulate and understand them.
This calls for a Copernican step: we must overcome a limit.
Just like we realized
we are not the planet at the center of the universe -
and we had to struggle to understand it -
and we realized we are not the ultimate animal species,
the final destination of every evolution:
we are one of the many species.
And we have yet to understand
that we are not the point of reference of every intelligence.
We are one type of intelligence.
There can be other types of intelligence.
Our machines are already intelligent, just in their own way.
We must treat them differently from us:
theirs is another type of intelligence.
The day we come to terms with this, it will be easy to pass the right laws
and teach the right things at school.
It's an important step
because coexisting means understanding, so that we can adjust accordingly.
The mistakes we made with the environment
were made
because we didn't really understand the underlying mechanisms for a long time.
In this case, we know what we can do
and we still have time.
At the end of the day, this is what being intelligent means.
Thank you.
(Applause)
