Part of my optimism is due to the fact that I'm in the Facebook groups and Discords for Shadowdark and Pirate Borg, where open calls for games are happening all the time, especially on Discord. It has literally never been easier to find groups or people to play with, whatever game one plays.
Yes, one has to vet those people and work out scheduling, but those aren't issues somehow unique to online play. In fact, I'd say discovering that you're in an incompatible group is better online, because you can just quit mid-game if you find yourself in a horrifying mess. In real life, if you drove 90 minutes to play with a new group, only to discover you were gaming in a basement filled with Nazi paraphernalia, it'd be a lot more challenging to get out of there safely and quickly.
I mean it in a value-neutral way. "I'd like to play with people whom I already know, on my preferred schedule, without major changes in my playstyle" is of course what I think almost everyone would prefer. It's not realistic when starting a new relationship with anyone. It's fact with no implicit judgement.
