I totally agree with you. Meetups is an awesome way of communication for developers. Learning new stuff, meeting new people, acquiring contacts or just socializing with people who work in the same field is very useful and beneficial. I bet it's fun for everyone as well.
Alas, nowadays I rely more on YouTube videos than real meetups 😩. I know I rob myself of communication, but I just don't have time. Well at least with videos I can be sure that I watch good stuff ☺.
