If Meta's Threads product is going to have ActivityPub compatibility as is rumored, then there's already an inroad about to happen. Right now, that's where all eyes need to be, to judge how you feel about the situation. For myself, I'm enthusiastic. If I have an easy means to communicate with friends who are mostly in Meta's sphere of influence, and organize local meetings, I'll move to that system almost immediately. Doubly if I have access from a browser

The challenge is, of course, that Meta (even as Facebook) has always been about deanonymizing users to better target them for ads. It's possible that Threads may not follow that trend, but you should expect that if you're communicating between, say, KBin and Threads, you'll have to give Meta your real name, and take any scrap of anonymity as a bright sign of hope.
