The most annoying thing when learning to program is that experienced programmers take your bullet points for granted -- and don't explain them well / don't explain them at all. But grokking those bullet points has a significant material impact on your ability to pick up the actual language itself later on.
The same is true when you're experienced -- programmers often say that programming is easy, which is because _syntax_ is often easy. It's the mechanics of how everything fits together that is difficult, and is often overlooked as a concept.
This was the point of the question :) To see what questions we need to ask if we're designing a software development environment in 2021. It may well be true that the current paradigm is sufficient: I was just curious what else came up.
