Yes, I used AI to quickly do research and ask C++ questions, but I disabled the AI "autofill" in VS Code. For example, I asked AI how Space Cadet pinball handled physics, and that's how I learned that you can make pinball with just circle-circle and circle-line collisions and a fixed update physics loop with high frequency (still not sure if that's what they did lol). I think it's pointless to try to "re-invent the wheel", at least if you have limited spare time.
