The future is offline.

My understanding is that the GDPR “right to be forgotten” applies to personal data. Are publicly available comments considered personal data?

You are American, although you've discussed Ryanair before, which isn't exactly American. You have a number of comments and posts about Japan, which is strange, although you do drive a Japanese car.

You live on Earth. Now that I won let’s go double or nothing. I bet I can guess where you got dem shoes at.

40 year old software dev in Detroit Michigan?

Not that I care, and that could be wildly off, but opsec is a wide term… and Claude one shot that… so safe out there bro, AI is wild

I'm pretty sure they can use the meta data the pull from your various interactions with search and the text you post online. These services build fingerprints of your habits using these techniques to follow you everywhere. At some point in the chain they could easily connect this fingerprint to your identity as soon as you log into and account that contains a piece of identifying information about you. The threat is real. I can foresee someone programming a terminal or app that obfuscates online behavior to avoid this fingerprinting in the future.

Unless I am misreading something. Take a look at surveillance capitalism to see what's possible right now. It's going to be 100x worse as LLMs become more advanced.

It's not the things you post online, it's the nuances behind the way you type and other ways to determine behavior that allows them to be able to build these kinds of profiles.

With low precision, you're in Japan. But I don't need the JPY. of course that could be obfuscation.

I skimmed some of your comments, You seem to be in the US, at least mid30s, you bought a .dev domain and run your own email? I would think those are possible leads. You really don't think you slipped up once or twice in 5 years of posting? I think an llm would go through all your posts and context of the posts to get. and that would be easier to check if you used any other social media with the same name and see if the accounts have similarities.
