confidence level: I am a physicist, not a biologist, so don’t take this the account of a domain level expert. But this is really basic stuff, and is very easy to verify. Recently I encountered a scientific claim about biology, made by Eliezer Yudkowsky. I searched around for the source of the claim,...
This is my article on one of the dumbest and most obviously false claims Yudkowsky has ever made, about biology not using covalent bonds.
His argument, as I understand it, is that he knew about the covalent bonds between proteins but didn't mention them because he was simplifying things for a lay audience, and that those covalent bonds don't matter because they aren't the "load bearing" elements in flesh.
There are two problems I see
His earlier statements suggest he actually had no knowledge of that whatsoever
I think his revised explanation is still wrong, because the extracellular matrix that holds cells together and connective tissue are composed largely of proteins that have these covalent crosslinks and rely on them for strength. When you tear a ligment it's not just van der waals and hydrogen bonds being broken, those alone would be far too weak.
What I mean specifically is, he wrote:
The nanomachinery builds diamondoid bacteria, that replicate with solar power and atmospheric CHON, maybe aggregate into some miniature rockets or jets so they can ride the jetstream to spread across the Earth's atmosphere, get into human bloodstreams and hide, strike on a timer.
Would "diamondoid bacteria" be inherently, significantly better at killing us? Or wait is he imagining the bacteria literally slashing at us???
From what I could understand is that he talks about diamondoid (and these other things) just because he has read one book about the subject. ‘Nanosystems’ by Drexler apparantly. (Never read it, can't say anything about it).
I'm not sure Yud is really engaging with what is being said vs just going on and on about how AGI can kill us all via nanomachines (son), because handwave theory something.
It's like he heard the phrase "flesh-eating bacteria" and decided they would be more scarier if they had tiny knives and forks.
The worst part is when they start to season you with salt and pepper...
