A degree is pretty useless, not just now but for a while. Companies prefer candidates with actual knowledge and skills about the tasks they are recruiting for. In the past, they used to hire top scorers and provide the necessary training for a while at their own cost. But students are not aware of it yet, they spend hundreds of thousands to get a degree but they realize about it's worth only when it's too late.
A degree isn't completely useless if your goal isn't just to be a low-level employee for life. Have you seen any company hiring CEOs, HR directors or assistant directors without requiring a degree?
Depends. Healthcare is always high in demand. Dentists, nurses, medical doctors will have no problems with getting a job no matter what happens. Even AI cannot take their jobs away.
But now we have technology where surgeries can be done remotely, a surgeon doesn't necessarily need to be present at the location. If I am not wrong, China has already demonstrated a surgery using robotic hands that was operated from a different location so it got some risks too.
But it only applies to minor surgeries, not to invasive surgeries such as opening the chest, opening the abdomen to intervene and treat diseases such as heart disease, childbirth...More complex surgeries still require direct intervention by highly qualified physicians as well as support from other medical staff.
Not to mention, after surgery, monitoring and caring for the patient's recovery is very important and only humans can do these things.
