I don't care about the rest of the post, or about arguing with you. I'm publicly correcting a specific, widely repeated, false claim. One which, if you take the time to read the links I posted, you will see is having a concrete negative effect on an industry responsible for real people's wellbeing. In particular (see the third link), ~50% of students considering radiology as a specialisation express concerns because of false claims its future as a job is under threat. These concerns contribute to hiring problems in that profession, which exacerbate a global staff shortage (first link) which results in worsened healthcare outcomes. There's a non-zero chance that correcting your statement will influence somebody considering whether to specialise in this field, and replying to your repeating of the claim as well as to the original instance increases that chance. I don't consider it pedantry.
