#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

and get more crowded as we get closer to eukaryotes, for instance.

#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

But you are still computing about 20 amino acids per second, right?

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

This is what you're generating every second.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

21 for bacteria, I believe 8 for eukaryotes or 9.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

I think it's great.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

I think, if you can show me a computer that does this, we are done here.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

Yes, you can show me that, but you cannot show me the one that has all.

For now.

For now.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

I think the more we learn about, and this is why early life and origin is also very fascinating and applicable to many different disciplines, right?

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

There's no way you see this the way we just described it unless you think about early life and early geochemistry and earliest emergent systems.

But going back to the biological component, all of these attributes that we think about life or that we associate with biology stems from translation as well as metabolism, but

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

I see metabolism as a way to keep translation going and translation keeps metabolism going, but translation is arguably a bit more sophisticated process for the reasons that I just described.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

It's a way to process materials, and it is inherently dynamic, and it is flexible, but it is not focused on repetition as translation does.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

So that's the main difference.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

Translation is kind of, in a way, just repeats, right?

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

So you have the metabolism that can synthesize materials.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

It creates or benefits from available energy.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

And again, it's a dynamic system.

Lex Fridman Podcast
#350 – Betül Kaçar: Origin of Life, Ancient DNA, Panspermia, and Aliens

And then you have computation that is inherently repetitive, right?
