Let's not get panicky.
I'm not sure it's right to assume that competent employees are either qualified /or/ diverse. Nor is it reasonable to fear that if you're not a minority then you'll be discriminated against, somehow.
It seems more likely to me that the company perceives in itself a monoculture, and is concerned that monocultures don't fare well in the long term. In order to avoid some future technological potato famine, they may simply be looking to hedge their bets.
Also, different points of view may help them gain insight into different markets, and so on, so it's not the worst idea from that angle, either.
Rest assured, there's always a market for excellence, even if you are a white male.
