EA becoming more intellectually sophisticated does not feel like a contradiction to what I was trying to communicate when I said intellectually stale (I may have expressed myself poorly!). As you said, there were more new ideas at the beginning but that is not the only way to be intellectually non-stale. While there may be more fine-grained detailed and possibly more true claims out in the EA community right now, that does not mean that participating in contributing these ideas is as accessible to people as it once was which is part of what I consider non-staleness to be.
I am a bit confused what you are trying to communicate when you say that it’s unfair to only look at the number of ideas.
