1. Start building stuff that is hard to build that requires touching these niche topics. Especially stuff you don't know how to build
2. As you encounter problems, you'll have to scour for solutions (AI doesn't know these things due to lack of training data). In the process you will find people who are also working on these problems. Ask these people well-formed, intelligent questions.
I find AI shockingly bad ad searching the web, as SEO blogspam sites heavily pollute AI context windows, while relevant and important resources are typically very densely presented reference material which must be constantly revisited.
