You can look to the past to see what this might look like in the future:

- Publishing in the digital publishing era.

- Indie Gaming in the Steam Greenlight era.

- Indie music in the digital recording / DAW era.

- Trying to make it as an actor or musician in general.

- YouTuber careers vs. "YouTube poop"

- Trying to make it as a streamer / influencer

Novelty, self-promo, luck, preparation, right place/right time, likeability -- there are lots of things that can come together to make it work. But it's still a lot of work.
