Apart from websites there are now other things that people deliver via HTTP and browser or a "web view". I would argue that the market for websites has shrunk.

Apart from websites there are now other things that people deliver via HTTP and browser or a "web view". I would argue that the market for websites has shrunk. There is a booming market for web applications that are just the best way to create a gateway between customers and ever changing business logic. In this space there is a proliferation of tooling and compilers and it's only going to get more complicated in the sake of betterment (JS as a compilation target). I'd focus on fundamentals, one of which is user experience. It doesn't matter if the flow is created in Go, React or closure, it still needs to be user-friendly, intuitive and secure at the same time. The domain knowledge is much more important than tooling.
