I think that number will grow as Twitter continues to decay. People clinging to the dead corpse is pretty cringe when it comes to Twitter.
Facebook is dead already I feel and most people I know using it are only in there for old people who can’t use anything else or for the marketplace. Under the same umbrella, instagram is dead unless you’re selling something.
Forums like Reddit and lemmy I think will last the longest, but even then when the toxicity grows and transfers over from Reddit to here I probably will stop using it as much
Also I say dead as in what it originally was has been lost in the wake of “influencers” and companies
