I have actually seen this with folks. Not in IT specifically but had a computer at work and had to login and theoretically do tasks with the computer more advanced than casual use of their own. Worse they can’t seem to use a local password manager to. IE update it when they make a new account or change their password. Its not just IT though as I see it with purchasing and billing like they did not do that a ton in their job. Or for that matter dealing with paperwork and beuracracy. I kinda worry about this happening to me as I age. I will admit it takes me longer to go through things than it used to. I like to think im evaluating them better but its honestly just can’t do the high energy frantic push anymore.
