I’m a developer with a very wide (and doubtless shallow) experience. And I love audio books.
I use Audible a lot but I do rue Amazon’s excessive dominance in this space.
There's no easy to find app that lets me easily search and play interesting articles , easily. There's also nothing that fits the context of doing something else and wanting a stream of interesting stuff according to a search query.
And recently there were big.leaps in quality if machine speech.
And maybe there's some role to play for hands-free dialogue with the machine.
And because it is a tool for learning , not just enterntainment , you may be able to justify a reasonable monthly subscription - if the app is effective.
