Apple Watch 12 offers a currently opt-in feature that basically uploads the conversations it captures into the cloud.

I know many people are concerned about completely offline hardware trying to sense you 24/7 for something convenient that you may want. For example, Mi 17 is capable of waking up the screen when you specifically move your eyes at it, likely thanks to a low power front camera sensor mode and Qualcomm's support for that. I liked it, but it probably eats battery.

That's one thing. But *uploading* constantly sensed data from people who never gave you consent for it, especially without homomorphic encryption (that was used with Enhanced Visual Search and still managed to break people's trust when it got enabled by default in update), is simply way too much. I've seen an article from TechRadar that completely omitted the important part: it is an online feature based on servers attesting their legitimacy. For something meant to constantly listen.
