Seems like a recipe for disaster.

Why not prove something simple out with a few million before dumping $140 million into it? Does what they're building really require that much software to be written before we know if it will work? I get that the founder has been successful, but wow.

I'm usually pretty wary when people say "OMG It's 1999/a bubble all over again!" But that is a pretty damn frothy raise, even if you're optimistic.
