That is basically a truth.

If you sit in IT people bubble then you might feel ashamed that you have to look up stuff all the time.

But technicians always had books like "mechanics guide" or "lookup tables" and they mostly knew which things to apply and where. Without training and experience you don't even know what to look for.

IT bubble people overestimate non IT people level of understanding, I see how "normal" people still struggle with basic text editing or using browser features that are obvious to me like "open link in a new tab". I am not talking here about my grandmother but even people in their 20's but just those non IT.
