Yeah, I'd hate to use this in an open-plan office (which is like 99% of offices these days) and even using it alone at home would feel awkward. I don't really want to talk to the computer despite what 1950's sci-fi books led us to believe.
It's a cool idea for the future when we have reliable EEG headsets or Neuralink or whatever though.
The only place I'd ever talk to a machine is my car. Instead of huge flashy screens that distracts and kills thousands of people maybe they could build a buttons + voice agent system that could actually be useful and durable. I hate to tap Waze/Maps/etc. every time when I go somewhere or that I cannot comfortably switch to specific songs en route without risking my life...
