Summary

Today's AI runs on neural networks, a design originally inspired by the human brain. As these systems grow more sophisticated, they're raising a profound question: Even if they don't work exactly like our brains, could something resembling a "mind" eventually emerge from the machines we're building?

I'm Rufus Griscombe, and I'm Caleb Bissinger, and this is the next big idea.

0:06.0

Today, is AI really that different from the human brain? Caleb, I thought it'd be fun to introduce this one together and share a little background on how we go about selecting the books and brilliant guests we have on the show.

0:39.6

Well, I mean, I hate to spoil the mystery for listeners, but I think the honest truth is that it's not a very scientific process.

0:46.2

We just comb through dozens and dozens and dozens of books until we find one that just grabs our attention, that just makes us sit up in our chairs.

0:54.5

And a couple of weeks ago, I saw this book called The Emergent Mind, How Intelligence Arises in People and Machines.

1:01.4

It doesn't come out until October 21st, but I sent it to you right away, and I was like,

1:06.3

how soon do you want to get these guys on the show?

1:08.6

Right, and clearly my answer was freaking immediately

1:11.5

because we recorded this almost two months before the book comes out.

1:16.3

So this, I think, is a treat for folks.

1:17.9

This is, I believe, the first interview that they've done.

1:21.4

And I, of course, feel entirely transparent and predictable.

1:25.9

As you know, I've been fascinated by this notion that our brains

1:30.4

and the brains of every other animal, even insects, are shockingly similar in their components

1:35.8

and structures, same neurons, ganglia, many of the same neurotransmitters as other animals.

1:42.9

And though individual neurons can't think on their own really at all, something magical

1:48.8

happens at scale.

1:50.7

Intelligence emerges.

1:52.8

And now we're building this AI in neural networks that are similar to our own.

1:58.4

And it feels like an opportunity to better understand ourselves and study how

2:02.6

that sophisticated thinking emerges out of relatively simple components in both silicon and

2:09.7

carbon, our own biology.
