I guess it's really a question for the programmers here...
As an example, it seemed clear at the time that OS9 didn't have the framework or capability to take us into this century, so what potential future computing developments could conceivably need something that OS X isn't capable of delivering, given the development of new layers for it, core etc?
What directions in hardware or software are being proposed that may necessitate an entirely new OS?
Apologies for the simplistic question, but I'm sure it's not a simple answer.
