You're right, and we absolutely should own the keys to our speech. That's not nothing.
But it feels a bit like we've been using a nuclear reactor to boil a kettle. Sovereign identity, cryptographic signatures, censorship resistance…. and we're, for the most part, using it to post takes and opinions.
"Forget social" wasn't literal. It was - don't stop there. Because right now that's where almost everyone stops.
Your signed post disappears into a feed. Your signed agreement with another person? That's a record that could hold up when money's on the line. That's reputation that travels with you forever... proof that doesn't depend on a platform staying online or a company staying honest.
Speech matters, we are all here using it for that. But what about everything else you do with your identity?
