> the majority is by far from much larger, public schools, like Berkeley, Michigan, Illinois, Washington, Texas, Wisconsin, etc.
These schools are very good btw. Berkeley is tied with Stanford for example, UI #5, Washington #6, UT is #10.
Conversely Harvard is ranked #15, but that's the things about rankings: they're often used to prune out people who don't "know someone", and when the metrics do not match someone's perceived "elite" status, they are ignored.
All of the schools you mention are attended by elites and commoners, produce talented people and untalented people, jerks and kind folks, and all the permutations of that.
I just wish we'd focus more on competent and kind, and less on connections or wealth - companies that do this will prosper IMHO, and companies that rant about "meritocracy" will wither as they drive away half the population.
Women are just as capable of coding well - creating a toxic culture is reducing your talent pool by half, something people obsessed with "facts and logic" should think more about. Insisting on "elite" schools when the good ones are public will also harm you long term if you're doing more cutting edge stuff.
