There are numerous alternatives that could (and hopeful should) replace FB - through what is referred to as the FediVerse - specifically via Pleroma, Mastodon, GnuSocial, etc. While admittedly mastodon is the platform that gets the most mindshare (and most users access the fediverse through it), it is not the only one...And much like email, users employing mastodon as "their tool" can communicate with other users who might employ other tools like pleroma, etc. Users have a choice! And, this federated universe is all aligning on open federated standards like ActivityPub [1]. So, yeah, there are options already in existence...and, the challenge is less technical, and more: "how do you get YOUR network of friends/family onto the fediverse?" Well, the migration has already begun, so it should only be a matter of time... [1] https://www.w3.org/TR/activitypub/ https://www.w3.org/TR/activitypub/
