First reported
Mindstream ran this on .
- IBM spent nearly $4 billion building Watson Health, an AI system meant to help doctors recommend cancer treatments globally, then sold its assets for roughly $1 billion in 2022.
- Doctors found Watson's recommendations frequently wrong or unsafe because the system was trained on trivia pattern recognition, not real patient medical complexity like multiple conditions or incomplete records.
