I actually think Ada has good potential as an AI adjacent language because the syntax is optimised for readability (I personally find it very readable too.)
I use clojure over common lisp because I find the ecosystem (libraries) a bit more approachable (feels like there is more web oriented stuff in clojure, plus gui support with javafx.) That said, the actual experience of working in common lisp is better (bit better repl/recompilation, conditions, native compilation.) Personally, I don't find scheme as practical for writing programs as either of these two options (too fragmented and/or niche.)
I'm in the same boat. It seems very common for people to feel burnt out in their careers after the first 5-10 years. Trouble is that the economy seems so intimidating right now.
When you put it like that, I kinda warm to the guy
