I doubt it's possible to draw a concrete line between in domain, and out of domain. Would you mind trying with a specific example? Because so much of engineering is understanding the interactions between systems. While I cant enumerate the exact asm codes, I do need to understand how the compiler is going to rewrite my function if I want to understand if a cast is safe, or if this function call order needs to be rewritten, or if I'm need a mutex to protect this from a torn read.

I think Mitchell Hashimoto as a pretty sane take here, where he uses LLM's to offload stuff he doesn't care about / want to think about so he can spend more time and brain power on the stuff that really matters. I tend to agree.
