Well, if there's one thing history has shown us (including the history of Apple's own insurgency against the PC), it's that complacency and stagnation make the incumbent a target for every newcomer who does have the drive to make a dent in the universe. And there are always a lot of people with that drive. This is how we keep ending up in the cycle of chaos > new paradigm > perfect software that probably should not be improved upon > collapse under weight of new features > chaos > new paradigm... repeat.
