Viable electric cars, light bulbs connected to wifi, Raspberry Pi, robots that run like cheetahs, quad copters, quantum computers...

But saying "I'm sure there might be a few but..." indicates your disposition will be critical of an objective response. You're probably going to argue that IoT light bulbs are just lightbulbs + wifi. But Edison didn't invent copper wire or glass, and nobody questions whether the lightbulb was an invention.

It's the same argument that no thoughts are unique, they are just derivative of prior thoughts. But the conclusion is hasty and incomplete. It's easy to deconstruct ideas (and inventions), a posteriori, into a collection of parts that existed prior. But the combination of those parts is what constitutes uniqueness.
