Shoelaces are a strawman. We've had laceable shoes for at least a century. Work any sort of tech support and you'll find that many people who are otherwise intelligent, capable, and at the top of their field look at a computer as a box that they do certain specific things to, and it does those few things that they understand. They've never needed to delve, so they don't, and things even as simple as Windows shortcut keys outside of Ctrl-X/C/V, or any browser use beyond open it, type in the search box can be utterly mystifying. Then take a person at that level of understanding who is paranoid that if they do something wrong they won't know how to get back, or that they'll lose their very carefully memorized workflow, and try to teach them something new. Even one small change that would save them surprising amounts of effort. Most people _aren't_ imbeciles, but when it comes to things they don't know on "that box", the edge of the world is very sharp and bottomless.
