I'm in a similar position. I did a bunch of courses on coursera, udemy, pluralsight, fast.ai -- because I like ML stuff, however, I'm pretty sure this will be just a hobby.

I've come to the conclusion that AI/ML is a winner takes all market, I really don't think we'll see millions of ML/AI "developers" like we've seen C++/php/.NET/Java in the past.

For the next 10 years I'll focus on kuberbetes/some big data/some ML, but even though I regret it, I think the only viable option is to get into management.
