I'm calling bull.

I would not trust some device to read my thoughts to write them to a Word document. Random thoughts are too uncontrollable.

I would not trust my phone to connect automatically to any device, I see that's a huge risk.

I would not trust my computer when I talk to it. Anyone can hear the conversation and it's disturbing in public spaces to other people.

We saw this happen with Google Glass. People need interfaces they can trust, that are not intrusive.
