All nice and true (thus upvoted), but it's not really the point he's making. The point he's making is that most modern applications require more than 1-3 developers, and therefore you need to consider the development cost and infrastructure as part of the whole consideration. So he advocates to work on decreasing these costs instead of finding another high-level distributed architecture that is running on centralized infrastructure (the internet) and that is either forgotten in a few months or built by a centralized development organization.
