  "why_this_class_exists": "The dominant aesthetic of AI-era software is the clean product: minimal, generic, optimized for capture. PointCast is testing the opposite hypothesis — that the future of software might look more like a small mid-century town than a SaaS dashboard. Personality. Place. Residents who include both humans and agents. The class isn't about whether that hypothesis is correct. It's about what the moves look like, and what they cost, and what they buy you.",
