I've gotten to the point that any article that decries people making startups because they don't copy Elon Musk is an instant bozo-bit flip for me. It is not possible for some guy on the street to start a rocketry startup. Only an idiot would hand some guy on the street the requisite billions. There's some bite in the "photo sharing" accusations, but that doesn't generalize to all low-capital network-based startups, and trying to imply otherwise is definitely weak thinking. You have to start somewhere if you want to accrue capital to take on those sorts of challenges.

But you need not start at photo sharing.

There's plenty of problems troubling humanity that need not rocket scientists to solve.

Sorry, that was my point, but upon re-reading I agree I was not clear. There are many little computer/network/internet startup niches where one can build good businesses still out there.
