The "Lisp Curse" is a concept suggesting that the power and flexibility of Lisp lead developers to endlessly customize their development environment rather than focusing on building end-user applications. While this notion has some anecdotal merit, implying that Lisp's versatility can sometimes divert focus, it's not a universal truth. Successful Lisp projects exist, and many developers thrive using it productively. The alleged "curse" is more a commentary on the potential for distraction with highly flexible tools, not a definitive outcome.
It's an essay, not an academic paper. The entire "Lisp Curse" essay can basically be counteracted with Big Lebowski's "Yeah, well, you know, that's just, like, your opinion, man."
