If it's vaporware on-device it's more evidence that it could have just been an app. Perhaps there was special on-device sauce coming in a future update, but as of now it's a client making http calls.
A clearly as yet non-existant feature. But would definitely require super obervation, recording, and control above standard android. Also insecure as hell.
It would be super dumbo-bonkers insecure if you werent actually running these "Generic app training" on your own device, but in some cloud emulation. yikes
This is as dumb as microsoft selling their next big feature of ai knowing how to control generic windows applications... that means they are going to record EVERYONES screens and actions without consent, we all know how microsoft respects users consent
Unless the plan was just to build a RAG source from your personal data, in which case it would be yet another underwhelming feature.
