There is ALWAYS an option...
One wonders what Intel might be had IBM picked the 68k as its processor for the PeeCee. Then (1980 or so as I recall) IBM had a chunk of ownership in Intel, so the choice was made for them. Fast forward to around 1990 when Apple, IBM, and Motorola chummied up and eventually decided to go the PPC route. Who knows what the world might be if they had different decisions. Sadly the 68k processors didn't get the backing from Motorola (Freescale, whoever it is now), and the shift was on again. It happens. For the most part if all you need to do is cycle the source through a different compiler chain, and you get something that "works", I suspect that nobody will really care. Rare is the application now that touches the instruction set directly, it is all some sort of compiled code.
Personally, the 68k instruction set was pretty good, and could have improved given the chance (*SIGH*). Who knows, maybe there is a 68k emulator that runs under ARM (at reasonable speed).
Life goes on.
