Don't make an enemy of the Steel Bankers or they'll send their Armed Bears after you.

isn't Steel Bank a play on Carnegie-Mellon (a steel magnate and a banker respectively)?

Funny, that.

Emacs-lisp is probably the single biggest Lisp in 2022, certainly by number of users, and most likely also by total SLOC in the wild.

No. That was decades ago when Gosmacs’s MockLisp was the dominant variant. Still, that was a useful interim phase until GNU EMACS came up to speed. It just wasn’t an acceptable Lisp.
