A doctor’s job is definitely much more stressful than a tech job. You are dealing with people’s lives every day and a misdiagnosis could possibly lead to someone’s death. Seldom do you have that level of responsibility in a tech job.
All we can really say is some doctors jobs are more stressful than some tech jobs. A podiatrist, for instance. It's critical work if you have a foot problem and a lot of pain, but it's not the same life and death situation as a ER doctor. On the other hand, if you're responsible for, say, Google or 911 being up, I dare say there's a very high level of responsibility.
