The platforms and their convenience that one "only" has to write the post yet the internet needs so much metadata, so it tried to autogenerate it, instead of asking for it. People are put off by need to write a bloody subject for an email already, imagine if they were shown what's actually the "content" is.
About convincing: get the few that matters on deltachat, so they don't need anything new or extra - it's just email on steroids.
As for Mastodon: it's still someone else's system, there's nothing stopping them from adding AI metadata either on those nodes.
It is, unless it's absolutely strictly local only to your devices.
It WILL be turned against you at one point, may it be a decline of insurance in the US, political imprisonment on visiting a non-democratic system, and so on.
I don't remember the link to the essay that defined public, private, and secret information. Essentially it said that public is ok for anyone to hear, private is something that shouldn't concern others, whereas secret is something that needs to be kept under wraps.
Under these terms most of what we're protecting with encryption is private - finances, health records, etc. I shouldn't concern others.
Sadly, it does, because the world is full of pieces of shite people who want dynamic pricing on health insurance based on medical information, and all the similar reasons, for example. (Note: I'm from Europe. The while insurance system that's in place in the UK is disgusting, and it's nowhere even remotely close to the pestilence of the US system.)
I'm conflicted with the whole encryption topic. We initially needed CPU power for it, now we have hardware, but that means more complicated hardware, and so on. We now have 47 days long certificates because SeKuRiTy, and a system that must be running, otherwise a mere text website will be de-ranked by Google and give you a fat *ss warning about not being secure. But again, we "need" it, because ISPs were caught adding ads to plain text data.
Unless there are serious repercussions on genuinely crappy people, encryption must stay. So the question is: why is nobody thinking about strong, enforceable laws about wiretapping, altering content, stealing information that people shouldn't have, etc, before trying to backdoor encryption?
It's a much bigger question why, such a completely natural and normal thing, like nudity, in the supposed to be educated - at least in basic biology - 2025, be made and exclusive thing.
The intro of the 1986 Once upon a time... Life animation series, that's the best human biology educational program that exists to this very day, starts with scenes many would classify as nudity - but it's also essential to the topic and the education it displays.
