Is that something you had heard or guessed? Did you attend a Lisp conference and talked to the people, where they were coming from (companies, universities, research labs, ...) and in what domain they were working on? Let's say, ACL2, a theorem prover written in Common Lisp. Unless what Mr. Urban tells you about Lisp users, they have a github repository. They have user/developer meetings. They even presented their stuff at Lisp conferences (I have attended one myself, where I saw a talk about it), wrote books about it, published hundreds of research reports, ... The user group shares > one million lines of Lisp code ( https://github.com/acl2/acl2/tree/master/books https://github.com/acl2/acl2/tree/master/books ), with many more lines of code developed by users. https://github.com/acl2/acl2/ https://github.com/acl2/acl2/ Workshops: https://www.cs.utexas.edu/users/moore/acl2/workshops.html https://www.cs.utexas.edu/users/moore/acl2/workshops.html How does that fit into your theory and what Mr. Urban wants us to believe? Here we have a shared large Lisp code base used at companies like Intel, AMD, ARM, ... where people collaborate over the Internet... how does that fit into your "go-it-alone culture of many of the practitioners" theory?
