@Impossible_PhD @matt not to mention LLMs are EXPENSIVE to run at scale, they're not something you can keep in a cloud and analyze all the data with unless you are gushing money like niagra falls (as is happening with OpenAI and similar) so the mass surveillance is mostly done on-device, which means you can easily control what data is analyzed by choosing what devices to keep.
If your device has an NPU and an operating system not under your control (non-rooted android, iOS, windows, etc.), it's likely going to be analyzing your data whether you want it to or not. Older android phones work with most apps anyway, because phones haven't really changed in years! Remember, regular data is practically useless to surveillance agencies (analyzing it is hard) but metadata is incredibly useful, so they'll try to make the analysis and such into features (tag your friends with their face on facebook!)
And to justify upgrading these new phones and spending all that money, they try to make it all features... they don't bother hiding away the surveillance but instead trying to make it the hot new thing... LLM summarization in iOS? also easy to do sentiment analysis (not necessarily what they're doing but it's easy). Recall in Windows is treated as a feature but is also a very searchable surveillance tool (that luckily got pushback but is still going to be activated and forced on users).
Recall got pushback because it's an incredibly tangible form of surveillance that's suuper easy for people to understand the implications of: "oh my god it screenshots what i'm doing? i'd hate it if some random person did that to me" is easier to understand than abstract privacy stuff like collecting sentiment analysis and profiling people for ad tracking.
