What is killing innovation? Something, somewhere in our modern world is putting the brakes on big practical scientific breakthroughs, big engineering accomplishments and big projects. Is it economic rationalisation? Patents and lawsuits? Capitalist monopolies? Wherever you look, "innovation" means "just a little bit better than that thing we had before". That's not innovation, it's optimisation. We're ramping down space programs, software is becoming more locked-down and restrictive, and we as consumers are losing control of the world. Call it whatever you like, but it looks to me like there's less big, cool stuff going on in the world today than ever before.
