I love the ARC challenge. It's hard to beat by memorization. There aren't enough examlples, so one has to train on a large dataset elsewhere and then train on ARC to generalize and figure out which rules are most applicable.

I did a few human examples by hand, but gotta do more of them to start seeing patterns.

Human visual and auditory system is impressive. Most animals see/hear and plan from that without having much language. Physical intelligence is the biggest leg up when it comes to evolution optimizing for survival.
