Your use of "the really hard problems" is revealing. Those of us who went to engineering school know exactly what you mean by that, because it's the way we describe the most challenging exam questions, projects, or open questions in the field. We can usually figure out those really hard problems if we put our minds to it. But for most tech startups, I'm not sure "the really hard problems" are the technical ones, because we are good at technical problems. Perhaps the really hard problems are how to get early traction, how to build something people love, and how to make the business profitable. Some of those hard problems might be easier to solve as a face-to-face team.
