I think you have some good understanding of parts of the problem but the ease with which you generalise is dangerous.

Getting from "I have too many bad experiences with highly intelligent, but myopic and immature software developers" to "I just think it's a really bad idea to try to hire 'extra smart' people (..) because it won't work" is pretty poor logic.

I think much better and productive statement would be "Hiring intelligent people is not enough to solve the problem."

It is much more productive because from there you can go to actually discussing what else is needed to make good use of highly intelligent people.
