- The limits to computing are not the limits

They're not the limits of concrete or steel

or anything like that in the physical world,

the limits to computing are the limits of your imagination.

people were fascinated by these incredibly complex machines

that could do things like process huge numbers

of mathematical equations incredibly quickly.

of the most remarkable people in the 20th century.

What he did was he invented a beautiful test.

If we ever get something that would passes it,

He never really expected that anybody was seriously going

to try it out, but actually people did try it out.

But it's been wildly misinterpreted, I say since then.

What Turing's most famous for is working at Bletchley Park,

a code breaking center in the United Kingdom

And actually, if that was the only thing he'd done

in his life, he would have a place in the history books.

But almost as a side product of his PhD work,

he invented computers, which are just any one of

the most remarkable sort of, you know, quirks of history.

he picked one of the biggest mathematical problems

whether mathematics can be reduced to following a recipe.

So the question that Turing asked was, is it the case

that for any mathematical problem that you might come up

with, you can find a recipe which you can just follow

in the same way that you would follow for arithmetic?

Incredibly quickly, within about 18 months,

mathematics doesn't reduce to following a recipe.

But the interesting thing is what Turing did

is to solve that problem, he had to invent a machine

and nowadays we call them Turing machines,

but actually it's basically a modern computer.

And he was one of the first serious thinkers about AI.

And so in 1950, he published what we think

If we ever achieved the ultimate dream of AI,

the kind of thing that we see in Hollywood movies,

that are conscious potentially in the same way

So Alan Turing, I think, was really frustrated

by people saying, "Well, no, of course these machines can't

be intelligent or creative or think or reason," and so on.

So Turing's genius was he invented a beautiful test.

who's sitting at a computer terminal with a keyboard

and a screen, and I'm allowed to ask questions.

but I don't know what's on the other end, right?

I don't know whether it's a computer program

He said, "Well, look, imagine after a reasonable amount

of time, you just can't tell whether it's a person

If a machine can fool you into not being able

then stop arguing about whether it's really intelligent

because it's doing something indistinguishable.

So you may as well accept that it's doing something

And so there are annual Turing Test competitions

across the world where people will enter computer programs,

and tell whether they're a computer program

Most of the entries in them are like these kind

And what these chat bots do is they just look for keywords

And they plug that keyword into a canned response.

And so they're really just trying to fool the investigators.

And I have to say- there's not really much AI

in most of those programs because they're doing something
