>I find that people that hop from "hot tech" to "hot tech" don't ever build up a depth of knowledge and understanding to tackle hard problems in an elegant way You immediately assumed that the folks I found are just jumping from tech to tech without building anything substantial. Which is probably also bias, just an opposite of mine. You also assumed that I didn't vet them or test them on "elegant solutions". Maybe your heuristic worked for you. But this heuristic, in my current situation is thus far working for me.
