Though I don't think it was the root cause of 68k's demise, offering poor backwards compatibility between generations was an unforced error by Motorola. Everything was changing so fast in computing in the 80s-90s, and Wintel's soft guarantee that you could just write/buy software and it'd work in the future was a big selling point.
