Feynman was talking about IAS in his days. I've been a PhD student in Princeton for 5 years, and there's plenty of interaction between students and IAS faculty. The difference is IAS people aren't responsible for their students. You could make the argument that IAS people aren't FORCED to interact with students, but the opportunities are there I think.
