Leaning hard into the IDE (or ChatGPT these days) because your language design is flawed is a hella/totally stereotypical "West Coast" thing to do, as described in "Evolution of Lisp", "Worse is Better", and "History of T", and exemplified by Interlisp and Warren Teitelman's "pervasive philosophy of user interface design" and implementation of "DWIM".
If your language isn't terribly designed, then your IDE doesn't have to be such a complex non-deterministic Rube Goldberg machine, papering over the languages flaws, haphazardly guessing about your intent, "yelling at you" all the time about potential foot-guns and misunderstandings.
As you might guess, I'm firmly in the "East Coast" MacLisp / Emacs camp, because that's what I learned to program in the 80's. I can't stand most IDEs (except for the original Lisp Machines, and Emacs of course), especially when they keep popping up hyperactive completion menus that steal the keyboard input focus and spew paragraphs of unexpected boilerplate diarrhea into my buffer whenever I dare to type ahead quickly and hit return.
But my point is that you can have and should demand the best of both coasts, unless you start off with a Shitty West Coast Programming Language or a Shitty East Coast IDE.
The problem is that west coast programming languages/ides are easier to sell. It genuinely pains me how accurate the original worse is better essay is.
