Everyone is different, but board layout is one area where I aggressively don't want any LLM input until such a time as it is as good at board layout as it is at refactoring code.

We're still a ways off from that, and that's likely because board layout requires a much more nuanced perspective of the enclosure shape, power requirements, heat dissipation, RF...

It's really not about placing ICs with caps nearby. I actually really enjoy that part anyhow. That's the fun part!
