Fed my startup plan to an AI that argues with itself. It told me we were 6 months wrong.

We were building AI code review for engineering teams. Enterprise. $50/seat. Seemed like a no-brainer. Then I fed the plan into something I'd been hacking on — thinking patterns that make AI agents argue with each other instead of just agreeing with you. It came back: "Engineering teams can't buy tools without VP approval. 70% of enterprises block it." That hit differently. It also said AI code review doesn't reduce work — now devs have to check the code and the AI's check. Stop selling to engineers, it said. Sell to security teams. Charge by fix, not seat. I hadn't considered any of it. We changed direction in a week. Same thing happened with Kafka vs SQS on a 3-node cluster. "Without the paper everyone cites, you'd just use SQS. You don't need a distributed commit log." We went SQS and wrote a note: revisit at 20 engineers. The output isn't an answer. It's a map — what everyone agrees on, what nobody's saying out loud, what the alternative path actually looks like. It's called PRISM. Open source, works with any AI, install is stupid easy:
