Aye--even if you've reached the point of thinking that the only role of a human is to feed good ideas into the machine, language is a thing that shapes thought--Lisp as a family is a thing different enough from a lang wanting to be a better C/C++ or a better Java that getting your brain thinking in terms of it can help you produce a different set of ideas (some of which may even be good ones). For me personally, it's really opened my mind to functional programming and intelligent use of recursion, in a way that I probably wouldn't have ever had cause to consider if I only ever concerned myself with the minimally convergent set of standard business langs, in the way that all our legacy code had been using them.

Of course, Lisps also seem to have the property of attracting people who genuinely like the practice of programming and, if it clicks with you, it has the property of generally leaving you really excited to write more of it. If you're hauling up and spending real American dollars to spend a weekend packed in a hall full of nerds to chat about a niche programming language, you're probably in that group. Consequent to that, it'd be a mighty small-minded thing to wonder what the point of joy is, when you could just be managing an agent swarm to write more enterprise Go code.
