The fundamental catch here is that 80%+ of the future benefit will likely come from the very thing that erodes privacy: deep integration and context. Imagine if a Gemini had your entire life in its context (haha scary I know!), prompting would be so much more powerful.

Windows Recall [1] is this for your PC activities (not yet fed to AI, but I see no reason to think it will stay this way). Meta is working on glasses to record the IRL part. But your phone is probably enough for most of it. Joining Zoom meetings with AI note takers is getting popular [2]. Not long until in-person meetings will have AI listening in from the phone mics, of course just to increase productivity and to summarize and remind you later. Convenience!
