@iscarlosmolero That's a really great question that I had never really thought of to be honest.
All that I'm aware of is that #lisp was used for a lot of research into artificial intelligence, maybe because it was mathematical and simple to build up functions and ideas? I'm sure I'm probably not even close to the target mark there. 馃ぃ
I may be nearing 50, but I'm still moderately young to lisp (last decade or so) as a hobby.
Definitely food for thought though. Excellent question!
