It's compatible with mastodon which already has a fairly large community (you can follow peertube users and their videos will show up in your feed.)

I think this kind of social network absolutely is the future because of how incompatible people's ideas about what is acceptable and what isn't are. If you find an instance who's moderators share your ideals you're good to go. No need to learn a new technology or give up most of your social network even!
