I would not dismiss his complaints as broad brush IT disparagement. Despite the title, I think the author is referring to the EHR (Electronic Health Record), specifically of Epic which is unique in that it is essentially a "benevolent tech dictatorship" imposed upon 90% of hospitals through owner/lead programmer Judith Faulkner at Epic (no medical background) lured initially by federal incentives then married to it in perpetuity. That's not really anything like operating system software you can uninstall today (e.g. Microsoft, Linux, Apple). With the onerous hospital system transformation contracts and non-disclosure agreements - Epic exec customers are more like cult followers than standard software consumers.
I suppose that's technically true although wikipedia states that she cofounded Epic with a medical doctor and is married to a medical doctor. As a software developer, I rely on subject matter experts frequently. I'm not an expert in radiology, chemical engineering, or any of the other businesses that I support.
