> All of medical science still imagines a world where humans are in "God's shape", denying the fact that we are machines made of systems of smaller machines.

No, it’s that these systems of systems are so incredibly complex that we still don’t understand many of them deeply. And misunderstanding the relationships of systems leads to major side effects and unpredictability.

If we understood these systems then we wouldn’t have vague success rates on things like drugs or surgeries - we’d be able to say “based on all of these factors this is the treatment that works for you”. But we can’t do that, instead we have trials and shrug and say “it works for most people so it’s worth using”
