Doctors, are there specialties/subspecialties you would advise AGAINST going into in the near future? Why/Why not?

I'm an IMG doing my (compulsory) internship, and for the past 3 years I've been thinking about interventional cardiology.

Sometimes I talk to notable doctors, and today I talked to an orthopedic surgeon who told me it would be a mistake for me to go into such specialty. He said the lifestyle and pay weren't worth it, and that interventional radiology would soon be taking over the work of interventional cardiologists.

Frankly, he was experienced enough and seemed knowledgeable enough that he practically put me in a mid-life crisis situation where I started doubting if I wanted to go into internal medicine at all.

• What do you foresee in the near future?
• Are there drastic changes happening in your field?
• Would you have picked something else had you known what you know now?
• Do new advances in technology and AI make you worry about your job security?

I did my elective in interventional cardiology – I liked the subject, the ability to immediately improve the condition of the patient, and the work itself was mostly fine by me – though I'm sure on-calls are not great.
