Oh yes, please tell me more about my personal experience, random stranger. Obviously, I’m going to come across more tech illiterate people on the phone, but to the extent that I did for the dumbest reasons would be enough for me to conclude that yes, most people have no clue what they’re talking about or what they’re doing. Literally way less knowledge than they should.
You came across many very dumb people, therefore most people are dumb. Seems logical. I work with thousands of meat workers, therefore most people must be meat workers. Your experience is more or less selection bias.
OK, I shouldn’t have mentioned my past job, but it goes way beyond just tech support. The tech support experience just highlights the fact that most people are tech illiterate. There are studies that literally confirm this. https://www.nngroup.com/articles/computer-skill-levels/
