Binary compatibility kept x86 dominant, coupled with competing platforms not offering enough of a performance or price benefit to make them worth the trouble.

That formula has completely changed. With the tremendous improvement in compilers, and the agility of development teams, the move has been long underway. People are firing up their Gravitron2 instances at a blistering pace, my Mac runs on Apple Silicon (already, just months in, with zero x86 apps -- I thought Rosetta2 would be the lifevest, but everyone transitioned so quickly I could do fine without it).

It's a very different world.
