I've also wondered why Medium doesn't deliver audio articles as well.

Audiobooks are in an upward trend and platforms as Medium might need to reconsider expanding their content delivery system. If someone wants to go for a jog and listen to a series of Medium articles (like an author's article playlists), why not give them that experience?

As a musician, you might also try to explore the NFT space. I've recently come across an interesting podcast episode that speaks about it, in case you're interested here's the link:
