Can't chime in on safety issues, but on usability: I know a physician who transitioned to using EMR roughly five years ago. It doubled the amount of time they need to take notes, to this day. They can't see nearly the same amount of patients they used to because so much of their day is spent going into and out of full screen surprise submenus in the EMR software and flipping through different tabs and re-entering information into multiple forms and scrolling through dropdowns with multiple hundreds of options. GP's post is 100% believable for me. It's nothing like Rust vs C89. It's more coding with punch cards vs an IDE, except the EMRs are the punch cards.
