Cost doesn't set price: how I got a product decision wrong 4 times in one day
I spent a day letting an AI agent research a product decision for me. It changed its recommendation four times. Every reversal was caused by the same mistake, and I didn't see it until the fourth one. The mistake is embarrassingly basic: I was estimating the selling price from the cost.

A reporter spent a day using an AI agent to research a product decision, only for the recommendation to change four times. The mistake, embarrassingly basic, was estimating selling price from cost. This led to four reversals: changing markets due to duty fees, using stale data, making an inaccurate cost-based price estimate, and finally realizing cost does not set price.
