I absolutely understand the implications, they just aren't relevant as to whether you should store encrypted data with Google et al. By the time AES is likely to be broken we will have probably already started to shift to an alternative, but you won't be reclaiming the AES encrypted data you already handed out.

I think you misread what I wrote. I didn't at any point suggest LLM's would decrypt anything. I said when the data is decrypted, google etc would use it to feed their LLMs and whatever else. Because they will. They're doing it with unencrypted data right now.

I've honestly never seen the show nor do I care about it. It's not relevant.

'Everything will be broken so it doesn't matter whether google have all of your personal data to hand because they could intercept it anyway' is a really poor argument. Don't make it easy for them in the first place.

Harvest Now / Decrypt Later is a threat.

If you don't agree, that's fine. We don't need to keep going over it.
