I don't know about the misguided part, but it's definitely not easier said than done, a lot of people are doing it (although juggling work and a kid is demanding). The response I'm getting from the kids is just awesome.
So, for ordinary engineers like me, the solution is simple: mentor those who you think are underrepresented.
BTW: it's a pity that in FIRST girls around encouraged much, most teams are more than 95% boys.
A white, upper-middle class student at an Ivy League, versus a black guy with a single mom from the Bed-Stuy housing projects. I don't think it's a very good comparison.
And I say this as a white guy with a working middle class upbringing who works on social networking software, and I still have a real hard time identifying with Zuckerburg.
And this is why I think the black incubators make sense. You can bring the idea of an incubator into the inner city and recruit young people of color and if a handful get modest success it will begin to breed something in their community.
All this is easier said than done and maybe even misguided, but I think that's the idea.
