Ask HN: How can a senior software developer transition into AI?

In my case my expertise is in JavaScript/Typescript & Java mainly, experienced with infrastructure, cloud & on-premise, security, managing a small team. I love what I do and I'm really good at what I do I believe, usually work on 1 or 2 side-projects on my free time, trying to find an idea that uses AI to start playing with it.

Would you just apply for jobs in companies that do AI? Do a Masters? Self teach with online course and then apply for jobs?
