> Jane Street and Two Sigma are sucking up all the talent.
This is the most made up thing I've ever seen on hn. Those firms hire probably 10 new grads a year (maybe combined!). Unless you're saying the collective talent graduating "high-tier CS programs" numbers in the 10s, this is literally impossible.
Way, way more than 10, but I agree with you that they are not taking even 1% of tech talent per year.
