Engineers are allowed to think of whatever they want on their own time. Do I need to remind you what Einstein was "supposed" to be thinking about when he figured out special relativity?
For those who can't see the dead;
"We have no need for 7 billion Einsteins. Humanity is a team project."
Then again, you probably can't stop them with snide internet comments, so this discussion is fairly moot.
Besides, why wouldn't a Team Humanity of 7 billion Einstein-level intelligences, with the same diversity of specific skills, be better than what we have now?
