Karpathy dreams of image-to-GTA: building walkable 1906 SF worlds from a single prompt

Alex Albert showed that Opus 5.5's improved 3D modeling and vision let you build an entire world in Blender from a single prompt — a historically accurate pre-earthquake Market Street, San Francisco, 1906. Karpathy amplified it, imagining converting arbitrary historical footage into full-fledged custom GTA-style worlds you can drop into and explore.
