On today the birthday of Grace Hopper, inventor of the compiler among other computer science achievements, I ask HN, why is the hacker scene and computing field in general so hostile to women and people of color? More specifically, hostile to black people. It's my opinion that diversity spurs innovation, is the scene really so short-sighted as to ignore this long-term failure to include anyone but mostly white males? For a group that prides itself in its inventiveness, it seems to be a dangerously closed loop. Thoughts? What can be done to change this?
