I recommend starting with basic YouTube tutorials, then do a game jam. The great thing about game jams is that it is zero pressure. The only goal is to try to make something playable. It doesn’t have to be grand in scale, you don’t have to write perfect code to make change and growth easier. Just slap something together in 48/72 hours or 2 weeks, depending on the jam, then move on.
LLMs are AI as it is defined in Computer Science, not SciFi. And the lane assist on your car might also be, although it may just be a well tuned PID for all I know.
