I guess you haven't been friends with many professional seamstresses or gear heads? They do that all the time to their "in group" the problem is, now that billions use technology, a lot of non technologists are mixed in with the "in group" and neither side has a clear comprehension of who are experts or novices. I still think shipping TCP/IP stacks in consumer OSes was a horrid mis-design for profit motives. The net was much more peaceful before it became about start ups and profit. @Lanthus
