He has never been great with computers (though he often reminds me that he successfully created a boot disk with virtual RAM to run Falcon 3.0 on my IIGS when I was a kid). He's not totally incapable of using modern tech, but I am his tech support and we still occasionally deal with basic stuff like how to forward in gmail or save a PDF on his phone.
I remember when his hospital switched to EMR. It was a nightmare for the first six months, but he eventually got the hang of it. Some of the other older docs requested assistants to help them but he was stubborn and prefers self reliance if he can help it and just gutted though it.
That was years ago and I far as I can tell the doctors in his circle are very used to EMR now. I hear some are even liking new AI features that listen to an appointment and automatically draft notes (that the doc obviously must review and sign off on).
My dad retired this summer after more than 40 years of 60-80 hour weeks saving and improving countless lives. He still struggles with computers, but I don't know much about medicine so it's more than a fair trade of advice for me.
