Slightly related since this one is a bit borderline, there should be a community/slack for people experimenting with automation/ml-driven passive income projects. I think it's time.
And tbh I don't think it needs to be projects that make $money. Any automation/ML based projects that make life easy for the coder should qualify. Eg: A simple Python script I wrote as hobbist helped me build a meme page with 17K fb followers when I was in school. I had no intentions of monetizing it. Just harmless fun.
Shoot me link if you get one started. :)
