> I recommend you watch some videos of people using an IDE/Emacs or some text editor with sufficient support like VSCode to write Lisp code interactively. How they build a program while it is running. But also doing mechanical things like navigation and structural editing.
Could you please provide a link to some example videos you recommend? Greatly appreciated!
It's tough to predict the future, especially since technologies change all the time.
But if you master the fundamentals of a particular area that interests you, you might be in a better position to respond to whatever is hot/upcoming at the time.
In Web there's always a hot new thing in frameworks/tools but the underlying tech/fundamentals have remained the same e.g. HTML, CSS, the DOM, etc.
