In my social and meetup circle, COVID coincided with all the organizers of my favorite meetups reaching the age where one generally starts to slow down, have kids, and possibly move out of the city for more space and calm.
At that point they had all been running their meetups for 5-10 years, so they were also established in their careers and didn't NEED them anymore. So while keeping an existing meetup running pre-COVID was not exactly easy, it was doable and familiar.
But now, 5 years after COVID, all the longstanding meetups are long enough gone that people nearly have to start from scratch. It's starting to happen, but is a huge uphill battle. For the most part, I suspect it will be a new generation of organizers, but they'll be learning all the same lessons again, in a much less interesting and more hostile tech environment.
