Paul Graham felt all development should be in Lisp. Problem is readability by maintainers in the future. To facilitate that, the number of characters in the comments would have to exceed that in the code.
Sounds like a problem that exists in every single programming language to date. And the reason that problem appears is not because of the languages themselves.
Of course. That's why some massive projects got abandoned because nobody understood the code they were originally written in. Does anyone even remember Emacs, or AutoCAD, or Datomic? There were companies that went bankrupt because their Lisp codebases became obsolete. Remember Cisco? Or Apple (those idiots tried to build their payment system in Clojure), or Walmart? Or NASA (before they succumbed to the will of evil Elon). Maybe smaller companies like Pitch, or Funding Circle, or CircleCI, or Grammarly? No? Sigh, nobody cares anymore about the history of dead programming languages.
We abandoned a project in Python. Is Python unusable?
