The technical challenge is actually the smaller one. The real one is to get people to care. Don't be tricked by the HN/techie bubble. Most people don't understand the problem, or don't see it as a problem because nothing smacked them in the face yet. Any attempts to explain it makes you sound like a lunatic to some, or just a bit of a worrier to others.

Whether it's targeted ads, or training AI on their data, or verifying their age and implicitly identity, or "fraud defense", most people happily take it in exchange for a convenient freebie which is why things keep escalating.

It's understandable, people are assaulted with all kinds of abuses from every direction. There are more immediate threats that they can grasp more easily so this stuff has to wait its turn.

Or don't approach the world with a fundamental mindset of having agency to (help) fix things they see as broken. Just because people see something as bad doesn't mean they inherently see a bright flashing line from that to "so I should do something about it rather than accept it".
