Pseudonymity has never been perfect for preserving privacy. Soon it may be pointless.

I avoid using similar user names and providing identical structured info, but I could see LLMs being able to unmask you from writing style and topics alone.

The fact that this one of the few things they don't fuck up should tell you everything you need to know about the true motives of those pushing this technology.

So the lesson to be learned here is if you use any writings as part of something devious or sketchy and don't want it traced back to you, use a locally-hosted LLM to rewrite your draft before posting.

The scary part of this is that they have all the time in the world to perfect this while my Reddit comments are just sitting there, waiting.

And now you understand why they are pushing for AI data centers everywhere.

So they can spy on everyone, figure out who is talking about what, and have it quickly identified and summarized, at all times.

Don’t just imagine this being about you and your own nothing to hide.

This is about squashing dissent, lying to voters/hiding vote manipulation, manufacturing consent, corporate espionage/market manipulation, basically anything you can think of that having advanced knowledge of would benefit them.

There is a reason they named the company Palantir.
