The main unsolved issue is Attention being Finite while Info is exploding.

Big Tech invading privacy was a response to reducing the Gap between Attention and Info (collecting likes, monitoring activity was required to produce a better news feed or search index). Decentralization, pki, moderation, safety etc dont really address the Gap. And quite probably lead to more info not less.

Its looking like if you build anything these days without thinking about whether you are reducing the Gap, you end up with strange unsolvable issues sooner or later.
