I've been reading similar statements every years since I started programming in Lisp in around 2000, and could easily find more of the same going back in Usenet archives and whatnot before that.

"Considered Opinion: LISP is Terrible" (Usenet, 1983): https://www.usenetarchives.com/view.php?id=net.lang.lisp&mid...
Excerpt: "I have been attempting to evaluate LISP as a programming language for VLSI design, and after having read MANY LISP programs, I have come to the same set of conclusions about LISP as a programming environment. To make LISP usable, each particular interest group defines/modifies/extends LISP for its own purposes. The result is a set of islands of users, each with their own "flavour" of language, which they claim is the "one, true, and holy LISP. I like the LISP data structuring; As a programming language I rank it in the same class as APL: useful, highly unmaintainble, very hard to document, and VERY unportable."
