When learning new stuff I consider 2 things:
- How much fun is the actual learning?
- Can I actually apply what I am learning?
So I would learn things that are either fun for you to learn or things that you can directly apply.
For AI this means you probably should learn about it if you are really interested and enjoy going through build-your-own-NN tutorials or if you have good chances of switching to a role where you can use your new skills.
Edit: Basically investing anything (also time) is risky. So invest in things that directly pay off or bring you joy regardless of the outcome.
