Surgical specialties aren't going anywhere as long as humans are made of meat that occasionally needs repairing. Bedside nursing is also key. Technicians who acquire imaging aren't going anywhere - no one is going to let a robot roam the hallways, taking x-rays of things autonomously.

Then no matter how algorithmic the first or second line medical treatment is, you're going to have patients that the guidelines don't fit neatly and need adjustment and you need people to clearly explain and convince patients of the treatment plan.

At a higher level you need people with the requisite knowledge to understand if scientific studies that show us who should get what diagnostics or therapeutics are reliable, applicable, cost effective, worth including in overarching guidelines.
