The following is a conversation with Sarah Walker, an astrobiologist and theoretical physicist

at Arizona State University and the Santa Fe Institute.

She is interested in the origin of life, how to find life on other worlds, and in general

the more fundamental question of what even life is.

She seeks to discover the universal laws that describe living systems on Earth and elsewhere,

using physics, biology, and computation.

As a side note, let me say that my hope for this podcast is to try and alternate between

technical and non-technical discussions, to jump from the big picture down to specific

detail research and back to the big picture, and to do so with scientists and non-scientists.

In terms, I hope to alternate between discussions of cutting edge research in AI, physics, biology,

to topics of music, sport, and history, and then back to AI.

AI is home.

I hope you come along with me for that wild, oscillating journey.

Some people message me saying to slow down since they're falling behind on the episodes

of this podcast.

To their disappointment, I have to say that I'll probably do more episodes, not less,

but you really don't need to listen to every episode.

Just listen to the ones that spark your curiosity.

Think about it like a party full of strangers.

You don't have to talk to everyone.
