Counter-points: Flying cars (bombs) are a dumb idea, the infrastructure to support globally broadcast 140 char messages is nothing short of amazing, and innovation is alive and well despite the financial service industries sucking up America's brightest minds : http://www.economist.com/blogs/schumpeter/2011/04/talent_and...
My thoughts exactly. The reason we don't have flying cars is not a lack of innovation, but rather that we don't really want them in their feasible form.
Further irony: Paypal options haven't been very easy or full functioning for Kickstarter projects and siphon off a percentage that could go towards innovation.
