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

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

#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.

#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?

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

Needs to carry out repetitive processes.

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

And it does the tasks and it implements an algorithm, but it is not dynamic.

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

So you see both of those attributes in translation combined.

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

It is repetitive, right?

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

And it is dynamic.

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

And it also processes this information.

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

So they are fundamentally different.

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

I don't know if you can get life if you don't find a way to process the information around you.

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

Yeah, and somehow that's what got selected.

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

Maybe not selected.

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

I don't know if it was accidental.
