The only way I can see to do that is to get more people that have interests, other than money, to join. However, that's like asking artists to come to investment club meetings. It's too boring fo them to return more than a couple of times.

There is a second topic that's common, unfortunately, it's notes about LLMs. I don't see people that have interests outside of money, or bent hammers, to be flocking here anytime soon.
