Artificial meat is harder than artificial intelligence โ€” Lewis Bollard

This is what you see with the history of breeding these chickens to be the kind of mutants they are today, where they've achieved a 4x gain in growth rates since the 1950s.

That has led to a 2x drop in price, and that has led to a 3x increase in consumption.

Dwarkesh Podcast
Artificial meat is harder than artificial intelligence โ€” Lewis Bollard

And because consumption has gone up so dramatically, and the suffering per bird has gone up so dramatically, that has outweighed the benefits of these birds being bigger.

Dwarkesh Podcast
Artificial meat is harder than artificial intelligence โ€” Lewis Bollard

No, no.

Artificial meat is harder than artificial intelligence โ€” Lewis Bollard

So I think there is an in-between ground solution now, which is the higher welfare breeds that we are advocating for producers to adopt are

are not 1950s growth levels.

Dwarkesh Podcast

They grow almost at 2025 growth levels, scaled back slightly in a way that enables much larger welfare improvements.

Dwarkesh Podcast
Artificial meat is harder than artificial intelligence โ€” Lewis Bollard

And so I think you don't have to go backwards to the level of these incredibly slow-growing animals.

Dwarkesh Podcast
Artificial meat is harder than artificial intelligence โ€” Lewis Bollard

Some people will want that.

Dwarkesh Podcast
Artificial meat is harder than artificial intelligence โ€” Lewis Bollard

I mean, there'll be a market for heritage chickens and people who are willing to pay for these extremely slow-growing animals.

Dwarkesh Podcast
Artificial meat is harder than artificial intelligence โ€” Lewis Bollard

But the more realistic thing at scale is going to be these ones who still grow fast and still get big, but do so in a way that doesn't totally destroy their bodies and cause them to suffer so much.

Dwarkesh Podcast
Artificial meat is harder than artificial intelligence โ€” Lewis Bollard

I agree.

Dwarkesh Podcast
Artificial meat is harder than artificial intelligence โ€” Lewis Bollard

I mean, this is the story of the chicken meat industry is they have just bred and bred.

Dwarkesh Podcast
Artificial meat is harder than artificial intelligence โ€” Lewis Bollard

So these animals suffer more and more.

Dwarkesh Podcast
Artificial meat is harder than artificial intelligence โ€” Lewis Bollard

And I'll give you another example of that, which is the breeding birds.

Dwarkesh Podcast
Artificial meat is harder than artificial intelligence โ€” Lewis Bollard

So the birds that they have have that are raised for meat are optimized to only survive until about seven or eight weeks of age.

Dwarkesh Podcast
Artificial meat is harder than artificial intelligence โ€” Lewis Bollard

And even by that age, a lot of them are keeling over, getting lame, collapsing.

Dwarkesh Podcast
Artificial meat is harder than artificial intelligence โ€” Lewis Bollard

But they're not at puberty yet.

Dwarkesh Podcast
Artificial meat is harder than artificial intelligence โ€” Lewis Bollard

So they need to raise some of these birds past puberty to raise the next generation of birds.

Dwarkesh Podcast

For those birds to not totally collapse under their genetics, they have to starve them.
