I think you are better off learning one (or two) of those things in detail as opposed to just browsing.

I am "management/director" level, so I don't need to go too much in depth in any specific topic. But I need to know enough to help my teams and clients and to make sound architecture decisions.

For instance AI, ML, Blockchain all have a lot of hype. You don't want to drink the Flavor Aid on these.

GraphQL is also quite controversial, it is connected with the theme of "APIs that take rather than give".
