After giving all of them a chance, I just pick the best one to build.

Background thinking is like brainstorming, in that good ideas can lurk
behind, and be inspired by, stupid ideas.

You are arguing for rejecting ideas ASAP because there's not enough
mental bandwidth available. I suggest that our brains are quantum
computers with essentially unlimited parallel-processing power, and we
can afford to give everything a chance, to explore the infinite
solution space for a while.

What's a simpler concept is that social pressures make most people
afraid of having unorthodox ideas.

Half of electronic design is psychology. The other 60% is packaging.
The rest is thermal.
