I think the GP's point still stands. Smart companies will have an advantage recruiting these engineers, because they have less competition, and so they will win. (Corollary: the quality of the team is the strongest predictor of success).

I agree. Anyone who would hire a worse employee because they don't like the other's {race,color,nationality,gender,sexual preference,...} is an idiot, and I wouldn't bet on their success.

That said, we definitely need some short term solutions too. "Evolution" isn't particularly helpful to those being discriminated against right now.
