I actually mostly built Lexicap so I could share a few snippets of Nick Lane ep :). (I already read the books so I'm ~familiar with the topics, these snippets are just personally newish+notable). (Maybe a great podcast app would make threads like this much easier!)
"A cell is basically just a micro version of the planet."
karpathy.ai haven't thought about it this way before.

"[Organisms] are just a kind of an outgrowth of the earth"
karpathy.ai (pourous, alkaline) hydrothermal vents on active wet rocky planet create a gradual path from "sterile inorganic planet" to "living cells". Pockets & membranes protect and power early life chemistry

"Basically, you're taking hydrogen and you're sticking it onto CO2 and it's powered by the sun."
karpathy.ai life is hydrogenating carbon dioxide. Photosynthesis takes it from water but you could also take it from hydrogen sulfide, ferrious iron, etc...

"How many alien civilizations are out there? Do you think?" karpathy.ai The whole section.
"I expect bacteria to be very common."

Ok semi-arbitrarily truncating here because there's too much to link otherwise :). My main interest in these topics is to understand the Fermi paradox: The impediments to life, the probability of overcoming them and the inevitability (or lack there of) of specific solutions.
