Tech has the following issues to greater and lesser extents:

* It gets in the way: confirmations, notifications, features that don't exist and can't be added, even when they're asked for repeatedly.

* It stops listening: freezes, overly-strict interaction requirements.

* It's not 100% safe, and thus not truly reliable.

Not all tech is like that. Or has to be.

Or, it's greasing the wheels of free-association until people skid out of control.

And since the 'world' of the chat is mostly epistemologically closed (except for Web search), there's no absolute tether point. Everything's subjective, and self-confirming.

I still think stylus support (both hardware but especially software) is going to be a killer app for these things. They've gone in the wrong direction for now, but some of the Asian phone companies (Huawei?) still have stylus support.
