If you've tried it properly and didn't personally found it compelling that's ok. I've seen people for who their mental model of how they think and approach computer tasks doesn't land to it, or people who just have other personal preferences. As for example of software made with a Lisp, I feel people are never happy with them, like a constantly moving goal post, but there's a certain chicken and egg to it. Some examples: - HackerNews - Emacs - LispMachines (the entire OS) - AutoCad (uses Lips as a scripting language) - Jak and Daxter (the first game) - Yahoo Stores (pre-sale) - Reddit (pre-IPO) - Datomic (no-sql tuple DB) - The flight system in the Boeing 747 Next (their latest 747 as of this writing) - Apache Storm (the distributed stream processor) - Walmart (they use it for backend stuff) - CircleCI (build automation) - Riemann (a high scale distributed event stream publisher) - worldsingles network (bunch of dating websites) - NuBank (a Brazilian bank) - ConsumerReports (all their backend) - The Climate Corp (agriculture software) - Roam Research (note taking app) - Kevel (ad server as a service) - HighSpot (sales rep software) - Reify Health (health related software) Now those aren't all Common Lisp per-say, but Lisp languages so Arc, Common Lips, Scheme, Clojure, EmacsLisp, etc. There's also a lot of use of Lisp that's not like a closed software, a lot of times it'll be a backend service or parts of a system is using Lisp, I know Amazon, Microsoft and Netflix have some such use, it's not wide scale, but you'll find some teams there using some kind of Lisp, as you'll sometimes see job offers that mention it.
