> This is exactly what Apple does

That is not true, even the puff-piece article admits as much if you read it carefully. This can be proven trivially: is Siri processed locally?

Answering only the trivially erroneous objection, and ignoring two other better-founded ones, does not reflect confidence in your stance.

In the footnote to the point gp was replying, I had said

> Until Apple does something truly radical (like 100% encrypted information that is processing on-device)

You can call it trivial, I will argue otherwise. No one knows outside of Apple how big a percentage cloud-based processing is, but my point remains - Apple's does what everyone else is doing, the only difference is proportion.
