Where to look for like-minded people to study in rare areas, for example, reinforecement learning?

Question

IT education

I realized that if you unite with someone, then the training goes faster and you find answers to questions faster. And most importantly, motivation increases many times over.
How can you find people close to your level to teach and share knowledge in rare areas such as Machine Learning?
In the social networks obviously do not find such people. I thought about making a video on my Youtube channel, but I think there will be a small conversion of people who also want to study the field and have about the same level of knowledge as I do.
Specialized forums like Stackoverflow don't like stupid questions, and they're made to solve specific problems.
