The patent system, like Bradbury's writing, exists not to promote the future but to delay it.
Consider: we've been people a hundred thousand years or so. We've had agriculture about fourteen thousand years. We've had bronze about five thousand years We've had steel about three thousand years We've had aviation a couple of centuries We've had rocketry and computers within living memory
At the rate the rate of change is increasing, it's clear:
The Patent System is the only thing holding off the Singularity!
