Waiting for the crowd means no vertical computing, no gorilla glass, multiple, ecosystems, Tandem OLED or thunderbolt five releases to a wide audience before most of the competition.
Features like Corning Gorilla Glass, tandem OLED and "vertical computing" should have been cut in favor of a GPGPU redesign. Apple Silicon is now dead-last in the GPGPU architecture race, in the middle of a $4 trillion CUDA market. Nothing that you listed is a $4 trillion feature, Apple absolutely should have put aside their pride and helped Khronos kill CUDA.
Not really “luxury”.
You just conceded the point. Only some businesses buy them, because they want to lure and retain expensive, white-collar talent.
No enterprise servers deploy to macOS. Nobody's edge compute or inference cluster is a Mac. Apple does not make hardware for those people, they are a luxury bauble company.
