It happens in all areas of everything. I'm convinced. It comes in cycles, because of generational retirements/career transitions. Younger/newer folks don't have the experience to know what the older/more experienced folks do. The older/more experienced folks do a bad job of documenting their experiences for the next group.
I'm thoroughly convinced I'm correct, but have no data to back it up.
We should do a head-to-head competition between two Grandmothers, one armed with an iPad2 using iOs6 and another one using iOs8 and let them do the same tasks, and measure the time it takes to do those tasks.
