Bring back the Alpha!
Now that's funny!
RISC was supposed to be big. PPCs,, I64, Alpha, SPARC, all tried to push this forward.
Will ARM succeed where others failed? Who knows. But no one forced X86s on the market. Apple could have continued to solder on without the switch.
This situation has occurred thanks to continued development that has allowed the X86 to have a performance edge while maintaining a low cost.
The phenomenon is purely market economics in action. No great corporate conspiracies are involved here.
