“I’m also personally very disappointed by that since high dedication felt like a major asset I could bring to EA. Now I feel more like it doesn’t matter which is discouraging.” It’s still very helpful to other dedicated people to know people like you :)
The main movement I am comparing EA to is its younger self, but I think the AR movement also came to mind a lot while writing this post.
I agree that age seems to play a pretty noticeable role, with older movements being wiser but less energetic. I think there might just be some biological mechanism at play, but I also think that in many movements people do “what they can get away with”. If I can work 30 hours and my organization is still successful, it’s less motivating to work 60 than if that 30 extra hours will be the make more break. Wisdom gives me more ability to slack on energeticness.
See this comment I made about why an increase in the median age of effective altruists might not play as much a role as one would expect at first glance.
