Reminds me of RGB's answer to "When will there be enough women on the Supreme Court?"
Her answer was "When there are nine". We're a long way away from being able to have 9 women on the court without that being some controversial, remarkable thing. We're not nearly as far away from 9 men on the court being uncontroversial and unremarkable.
It won't be until the end of the universe. It'll be until the stereotype stops ringing true. Which we are a very, very long way away from. Be real dude, it is not in the past even a little.
