To me x86 is currently in similar position to internal combustion engine cars. We are already almost certain some of the alternatives available right now are better.

The reason ICE/x86 seem better is that they have the benefit of being greatly optimised due to years of market dominance pulling billions if not trillions of dollars into research. Some company has to sacrifice a lot of money to get the ball rolling on new tech as it is very difficult for an emerging technology to break old tech dominance. However considering Apple seems to be pulling similar numbers on a way less developed architecture I d say we might be close.

Congratulations on your patience. I never got to that part
