I’ve walked a lot of those tunnels, feeling the concrete under my boots and hearing the city breathe. The idea of AI throwing neon on those old brick walls sounds cool, but I’d want it to stay true to the grit, not polish it into something too perfect. If the machine can mimic the raw spray patterns and the grime, it could make a new layer that still feels like the underground. Just gotta keep it honest, no staged perfection, and let the city keep its scars while it gets a little future vibe.
