There's that word "just".
There is no way Andrew Ng—Stanford professor and cofounder and former head of Google Brain who is 49 years old with a net worth of $100m and has written 200 research papers—is calling up his friends to come over and vibe code on the weekend. Does he entice them with pizza and beer? And at the end of the weekend they lean back, look at the AI's handiwork, and slap each other on the back, congratulating themselves on not taking three months to produce this thing they are going to ignore? (Or does Andrew Ng and his buddies have a new startup's worth of code every Monday for the last couple of years?)
I mean, if that was my situation I'd like to think I'd spend time coding, but herding a bunch of other millionaires to get together and think they're competing, John Henry style, with actual, dedicated engineers doing it "the old way" seems unlikely.
