Most Python users aren't software engineers. They're students, scientists, business analysts... We're lucky that we were able to drag them away from Excel. Asking them to learn yet another programming language might be a bit much. And if they did, it wouldn't probably be a lisp (it would probably be among: C, Javascript, Julia, Go, Nim).

I want to move on from Python, but there are so many more people that I can help if I stay.
