Just because robots can be more efficient than humans and can make certain processes cheaper doesn't mean they'll always come out on top. Case in point: Johnson & Johnson is pulling its anesthesia robot called Sedasys from the market over poor sales, according to Outpatient Surgery and Anesthesiology News. It was once a promising alternative to anesthesiologists, since it can bring down the cost of administering sedation from $2,000 per procedure to $150 to $200. It eliminates the need for an anesthesia professional, after all, as it allows any nurse or doctor to put a patient under in the operating room.
