Taking a risk of being boring and staying technical... I would say - cloud, distributed systems, security, security, security and then some more security. Then AI/ML on the "how to use it" level (the math can be fun, but unless you plan to be a data scientist, knowing it from a developer perspective is great too)
In the cloud technologies, I would focus on serverless. I see serverless as basically just another abstraction layer beyond containers. You shift the burden of managing all that to the cloud provider. Even if you are fluent in k8s, using managed services / databases and letting someone else do the heavy lifting while you focus on just code is very rewarding.
