Positive Read

Users expressed amazement that an AI could build a full 3D physics engine and quadruped simulator from one prompt, citing advanced features like rigid body dynamics and WASM compilation as genuinely impressive.

Based on 5 visible X reactions from 11 accounts; directional sample.

@cloneofsimo yes! I'm so glad they finally bought some 3d / IK envs and improved RL there - makes my life way less painful

@cloneofsimo yeah it is kind of insane dude
