Actually the radiologists job has proved difficult to either move overseas (requires US credentials) or automate (CAD still generates a ton of false positives). A radiologist still makes a considerable salary and is the R in the ROAD to success. Plus advances in continuous imaging and interventional procedures make it unlikely that they will see any significant decline.
Exactly right, it seems many people assume that automation or offshoring will be a smooth and seamless process with no trade-offs. That's not the case at all, offshoring and automation present their own kind of problems.
