Why can't developers spot the obvious vaporware ethereum?

Why can't developers spot the obvious vaporware ethereum (the world computing project with bitcoin technology of individual validation)?

With basic understanding of the technology you can know that their claims are outlandish. How can an individual verify that the unbounded computations on this network are correct? https://bitcointalk.org/index.php?topic=1427885.msg14601127#msg14601127

Every naive developer I meet thinks this is a legitimate project. Why as a profession do we accept projects with spurious claims? Is Software Engineering a profession or does it move too fast for anyone to know what is going on? Is cryptocurrency and token sales a corrupting influence on this profession?
