I believe the most computer proficient people were born between 1975 and 1995. Before that and they were too old to figure it out without a lot of effort. After that they grew up with touch screens and it’s all just magic. Right in the middle we were able to grow along with advancements in computing.
I was teaching a class with mostly students born after 2000. One of them had never used a computer with a keyboard and mouse. Never used folders and files. Kind of blew me away.
