My strongest advice to you would be to not burn the candle at both ends during this time, and to rest and relax without worrying about what the future holds. It's often only in times of respite that one truly understands what they want to pursue in the future.
Ask yourself if you're embarking on this new career path out of intrigue or necessity. If you're doing this because you're worried where your next paycheck is going to come from in 3 months, then allow yourself the time to think clearly about what you actually want to be doing instead of where you think the industry is going, what jobs will be available, etc...
If you're genuinely interested in AI/ML topics then by all means go for it, but don't think you are "wasting time" by not studying whatever is hot right now because it will always become a back-end CURD work, nothing cutting edge situation if you're not interested in what you do.
I'm only giving you this advice because no where in your post did I see any mention about genuine interest in any of the topics you mentioned, my read on your situation from this post is that you are worried about your eligibility of employment and want to avoid being left behind once AI takes everyone else's lunches.
If it's any consultation I think we are actually very far away from that happening and the vast majority of people who say otherwise have a financial position at stake unless they can get you to think that as well.
TLDR: relax and take some time to think about what you actually want to do vs what is going to be able to get you a job in a few months time, you will be much happier in the long run for it. I know a lot of Crypto / Web3 people who could not wait to get into the space 2 years ago but now are desperately trying to get out after rebranding themselves. Not saying that AI is like this completely, but again know thyself before making any big career moves like this.
