How do I pivot?

I'm a 35 year old full stack software engineer with a Bsc in software engineering. As a contractor for the last 10 years I have earned very well. But I no longer like my job. I haven't for a few years now. I always talk big at parties about us being on the verge of huge changes, automation and AI, basic income, yadaya. And I really believe it. Yet I am not contributing to that, its just talk. If I dig deep, and ask myself what do I really want to do, putting aside old fears of math, and disregarding income then the answer is easy. I want to contribute to this movement, even if it's small. It really matters, it's not just another web form. What could I realistically do though? I have the means to support myself for years without income. - A full time masters (age might be a bit weird) - Udacity DeepLearning into the AI programme - Something else? I'm posting for very general advice from my peers. A small sanity check before I quit my job and have my midlife crisis - as others might frame it :)
