As somebody else with a game engine that has its own scripting language:
AI is incredibly good at making scripting languages with your ideal dream syntax/functionality. It's pretty fun to use it.
(No, neither my engine nor my language is worth using and never will be)
I really don't want to use AI for my project. I love writting code by myself, and except for very few specific things, I didn't use it in this project. But for the language i actually didn't use ANY external sources, including google, tutorials, books. wanted to figure it out by myself. so maybe i'm kind of weird in this stuff
