#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

It's kind of the semantic grammar I'm talking about.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

about language.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

I mean, we kind of know that when we set up human language, we know that it has certain regularities.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

We know that it has a certain grammatical structure, noun followed by verb, followed by noun, adjectives, et cetera, et cetera, et cetera.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

That's its kind of grammatical structure.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

But I think the thing that ChatGPT is showing us is that there's an additional kind of regularity to language, which has to do with the meaning of the language beyond just this pure part of speech combination type of thing.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

And I think the one example of that that we've had in the past is logic.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

And I think my picture of how was logic invented, how was logic discovered,

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

It really was a thing that was discovered in its original conception.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

It was discovered, presumably by Aristotle, who kind of listened to a bunch of people, orators, giving speeches.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

And this one made sense, that one doesn't make sense.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

And you see these patterns of if...

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

the, you know, I don't know what, you know, if the Persians do this, then this does that, et cetera, et cetera, et cetera.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

And what Aristotle realized is there's a structure to those sentences.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

There's a structure to that rhetoric that doesn't matter whether it's the Persians and the Greeks or whether it's the cats and the dogs.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

It's just, you know, P and Q. You can abstract from the details of these particular sentences.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

You can lift out this kind of formal structure, and that's what logic is.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

The fact that there is an abstraction from natural language that has where you can fill in any word you want is a very interesting discovery.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

Now, it took a long time to mature.

Lex Fridman Podcast
#376 โ€“ Stephen Wolfram: ChatGPT and the Nature of Truth, Reality & Computation

I mean, Aristotle had this idea of syllogistic logic,
