Viggle Founder Claps Back at World Labs: JST-2 Is Native 3D, Atlas Takes 15 Minutes

On the day World Labs launched Atlas, Viggle founder Chu Hang posted a direct comparison between JST-2 (released October 19) and Atlas:
- JST-2: Every extension is native 3D, generated in about 1 second — the next room is ready as soon as you pass through the door. Built on a physics-native architecture, it models persistent "atoms" in 3D space, where 3D is the output itself rather than a post-processing step.
- Atlas: Every render is a 2D frame displayed as a point cloud; converting to 3D splats is a separate step that costs 5,000 credits and takes about 15 minutes.
He also pointed out that World Labs has raised over $1 billion while Viggle has raised less than $30 million, hinting at the potential of this architecture once scaled. JST-2 is available for free trial.
