I was hoping it would address Lisp.
Lisp is fun. The interactivity and instant turnaround of a Lisp REPL is still rarely matched in other languages. Common Lisp also solved a significant issue other languages didn't address well until much later: the ability to write high-level code that was fast on cheap hardware around the turn of the millennium.
Lisp didn't get popular around the turn of the millennium. Success stories like Naughty Dog, ITA, and Viaweb were rare, and the dominant languages seemed to be Java and various scripting languages starting with the letter P.
I often hear about lisp but never actually figured out what tooling you need Is it interpreted or compiled language? Why should I use it instead of any other languages?
I really enjoy writing lisp but the ecosystem of libraries is a barren wasteland.
Try to find a TLS library for Common Lisp that doesn't rely on openssl, for example. Last time I looked the most mature library was marked 'experimental'.
Hah! SO MANY LANGUAGES got skipped, even from my own CV. I wanted to address Louis/II, for goodness' sake, but it's a CODASYL tool, and not a lot of people remember CODASYL from experience. (Nor should they: I liked it, but... nah, RDMS won for good reasons.)
Lisp is certainly fun, and it lives today and is influential today in multiple environments; I have a Clojure app I work on for my own amusement. And it does have commercial appeal, but it's limited; the three axis thing applies.
