I have none. Do you? I'm working off first principles, which you agreed to. You're the one asserting mobos are better. Maybe they are. What proof do you have?

That's not the comparison. It's not washing machines versus space craft. It's washing machine knobs versus washing machine mobos.

Your analogies are again inapt. There may be minimal complexity needed to achieve a function. And the quality of any given part may be very high. But if machine 1 can accomplish a task with 40 parts, and machine 2 can accomplish the same task with 250 parts, then machine 2 will fail more often, ceteris paribus.

Isn't it just a basic principle of engineering that complexity and durability are inversely related? More stuff means more stuff that can break.

Aunt Sal here. Yes, knobs are better than this fancy electronic crap that breaks. Bless you.
