Does most of what you listed matter? Yeah - I know, it matters to make money(!). But it all looks really similar to me. If, instead, a new language taught you more about recursion or typing or a different way to view program structure, isn't that more valuable than learning the latest JS framework? or Azure? What does Azure really offer from a learning perspective? You know, I use TypeScript a lot, but it has taught me absolutely nothing fundamental, and has not made really made me better at anything other than Typescript. Playing around with something like Haskell made me think about some pretty fundamental structural and domain modelling questions, which I feel, although perhaps cannot prove, has been much more valuable.
