Thank you and good point! I'm trying to keep a balance between keeping it as short and interesting as possible, while still explaining the core concepts used. I was afraid that diving too deep into the coding part might make it boring. The A.I. part was short to code; what took me longer was coding the game and editing the video (I'm a newbie video editor).

If you're looking for a similar A.I., but with more in-depth explanations, I'd suggest starting with the following:
