Write a post, a listing, a product or a headline, and 10,000 computed AI residents read it. The 600 it should matter to see it first, and it reaches the next 1,500 only if more readers were glad than annoyed, so a weak text dies for half a cent and a good one reaches everyone in 14 seconds. You get who stopped, liked, reposted or blocked, by interest, job, age, city and budget; the questions buyers would ask a listing first; and a demand curve over a product's price ladder. No sign-in.

Could you build this?
Partial Simulating a cascade of 10,000 synthetic persona reactions with viral propagation dynamics requires low-latency parallel LLM orchestration and cost-effective batch inference that quickly becomes expensive or slow without specialized architecture.
What it would actually take: The architecture needs an agent runtime engine capable of sharding 10,000 persona state vectors across an embedding space to calculate topical affinity, then invoking quantized local models (or ultra-cheap batch API calls) to evaluate sentiment thresholds in tiered waves. The hard part is managing latency (14-second target) and compute costs (sub-cent budget per cascade) without blowing up token usage.
