Nice read but falls into a vast reductionist trap, a lot of survivorship bias dressed up as design philosophy or strategic bets. The context of decisions made decades ago != now, people were working under different constraints etc. Trying to frame the avionics example as the "subtractive" innovation is the most egregious, transistors were over 1000x times smaller, weight wasn't even a consideration.

I wish more people realized this
