It's amazing how much industry changed CS in the last decade. Significantly more than Academia. Resources is part of it of course, but I also think that the majority of best people in CS choose research labs in industry over academia. No surprise here of course - if openai offers you more than $500K a year, why would you go to academia, make peanuts in comparison and worry about politics for your tenure? Then when they get bored at big tech they raise money and start a company.
