Interesting that most of the issues seem to be UI problems - or rather, the idea that we don't need physical switches anymore because the phone is just the universal remote for everything reveals itself as incredibly stupid.

If we're already struggling with phone addiction and an out-of-control attention economy, probably the last thing you'd want is to constantly be forced back to your phone if you just want to do basic household things.

Also, I don't understand how anyone could think that random passcodes in the place of what used to be a button would be good UX.
