We, as SW engineers, have been doing that to many industries for the last 40+ years. It's silly and selfish to draw the line now that we're in the crosshairs.
Computers themselves replaced computers (yeah, a job title). Your medical software certainly automatizes someone else's job, otherwise no one will pay you to write them. You just don't care about them.
Or you do, but you believe it's worth it because your software helped more patients, or improved the overall efficiency and therefore created more demand and jobs - a belief many pro-AI people hold as well.
My comment wasn't about you in particular but the industry as a whole.
Much of the software written historically is to automate stuff people used to do manually.
I'd wager you use email, editors, search engines, navigation tools and much more. All of these involved replacing real jobs that existed. When was the last time you consulted a city map?
