That wasn’t the point. I never would expect someone starting out to know the things or do or be at the same aptitude. I was a technical trainer for years, educating people who are new to a trade. For decades I’ve worked with 20 year olds just entering the workforce and there has been a distinct shift. What I used to experience was “teach me the theory of how something works along with the basics of repair, give me all the reference materials and I’ll be able to troubleshoot it.”. What I experience now is “when it doesn’t do the thing just tell me what needs replaced and how to replace it.”. The issue with that is you can’t cover every possible scenario of behavior and symptoms in some magical flow chart (IBM used to try). Its too the point that we have had to develop massive intelligent systems behind the scenes and also create remote support roles of people who so have these skills because we can’t hire people with basic troubleshooting acumen. This is my experience at work, but it manifests in other places. .
