When I was in High School and Some College, mid to late 80s and Early 90s, I worked at several parts stores in town. We used to look everything up by parts catalogs. As I was leaving the parts business, they were getting the computers to look up the parts. I think this is where the gap started on knowledge. Now they rely on the computers even when they do not even know what the part looks like. Also lack of training.
