After learning Python, I wanted to take the next step and find what was better. I looked into a lot of languages reading books on Haskell and Lisp and many others. At least for my use cases (desktop scripting, numerical work... etc) I didn't find Lisp to be superior. Most of what I actually needed to do could be done simpler in Python. Python's REPL isn't near as good as CL, but it's good enough. Then the batteries included was huge. So practically any task I could whip something up pretty quick. There are definitely some areas where Lisp is obviously superior to Python such as performance of plain code or things such as grammarly that would've likely been harder in python. I just think for the vast majority of programmers, enough good parts were pulled from lisp.
