Here are a couple of ideas:
- Nextcloud to host your files and replace GDocs/Office
- Home Assistant to control your smart home
- Plex + Radarr/Sonarr to replace streaming sites
- RSS Feed Reader to read news and blogs (sorry can't remember the name from my phone)
- Single user ActivityPub instances
- Host your own blog site
I'm sure there's more
That's always been the case, though, imo. People had to make time for art. They had to go to galleries, see plays and listen to music. To me it's about the fair promotion of art, and the ability for the art enjoyer to find art that they themselves enjoy rather than what some business model requires of them, and the ability for art creators to find a niche and to be able to work on their art as much as they would want to.
