It seems like having a website open and available on the internet is getting practically impossible to manage, with bots accounting for more and more traffic. AI has gotten to a point where it can circumvent just about any form of captcha, sooooo, what? Does "the internet just get abandoned in favor of some other, better technology that we hope crops up? Does it fade away? Do the real nerds start their own separate internet, and not let companies in? I donno, food for thought I guess.
I could see, eventually, a public key reputation system where content is signed and you can filter what’s coming at you to just keys you trust, keys your friends trust, however many Kevin Bacon’s of separation you want, or just the entire firehose.
Society will have to get better at managing their private keys first. And then publishing tools will need to bake in signing features.
