Theory: is #Emacs being “good enough” why no #Lisp has a fantastically integrated development environment (including GUI toolkit) like every extant Smalltalk implementation has? Because as far as I can tell, Lisp machines *did* have a Smalltalk-like environment, but since Emacs existed nobody bothered to try implementing an equivalently featureful environment after Lisp machines stopped being a thing
@nytpu my theory is that for a long time unix has been such an amazing text environment that opens emacs up to being lispy in so many other environments. Smalltalk has always seemed like a very shiny box to be locked into.
