I agree with the author about the potential of audio interfaces + some simple additional inputs + integration with certain apps.

For me personally there is a suite of tools involving audio books and note taking that would change my life: A remote with a few physical buttons to rewind, switch to record-mode, skip sections. Speech to text with full text search. Voice recordings tied to what I’m listening to. Basically, I want to be able to work through a difficult audiobook while walking around.
