A lot of people think radiologists just look at images and spit out findings. Radiology is a lot more complex than that. We are far from AI being able to interpret a study to produce a full report autonomously without oversight. Most of the people perpetuating this myth are techies/data scientists/other medical specialists who have no idea what radiology is about. Even if we had autonomous AI, it would take years for it to be accepted from a regulation perspective. For example, a cardiologist needs to sign off on every EKG despite the available crappy "AI interpretation." And an EKG is a million times more simple than a portable chest xray...
Currently, there are a several simple AI algorithms that are being tested at a few institutions. These algorithms pertain to very mundane, basic tasks that a radiologist would gladly give up to improve efficiency. Tasks including pulmonary nodule followup, mass measurements, vessel measurements, etc. Nothing remotely close to feeding a computer images and getting "Impression: Acute Non-perforated Appendicitis" reply in a few milliseconds.
Again, non-radiologists tend to have an over-simplistic view of radiology. Radiology is one of the most complex fields in medicine. If we ever reach a point where radiology is replaced by AI, then all nonsurgical fields (excluding maybe pysch) will also be wiped out as well.
As for you question, other than the cool/chill personalities, radiology and anesthesiology are completely different; one is very hands on while the other is very cerebral. Choose your specialty based on what you'll enjoy doing rather then the expected job market. Nobody can predict what will happen in 7 years.
