It would be nice to have places like this open to the general public and not gated off like universities are. There are a lot of people who become interested in these things after university, people who didn't attend university that are interested in them, who were interested and involved in these things while they were in university but then drifted away from them, etc.
It seems like we'd be better off trying to encourage the public at large to continually improve (and also connect more with their community and improve civil society) than acting like all of this should only exist in a 4 year window that many people aren't even a part of.
