Huh, they won't get pay day if no one use their products. And there are plenty of examples of failed products. If people have idea and execution capability for sustainable progression they can very well try outside the valley. It is not like companies don't start outside valley.
which is why the majority of the startups fail and then a lucky unicorn comes and funds the next cycle. look at how many poor ideas got massive investment on the bet of payout; so many blockchain companies and none solved a real world problem. lots of potential investment in things that could have greatly helped many more people in the world, but instead invested into a technology looking for a problem.
I agree that the vast majority of the blockchain companies were "technology looking for a problem," (or at least, technology looking for another problem besides money ledger) but blockchain really was (is) a pretty damn good technology. The most unfortunate part of it is that the only thing it may really stick for is DRM :-(
