This spirals as well: I've spent quite a lot of time recently helping people at the early stages of learning programming, and it's taken me a while to stop becoming frustrated with their misunderstandings. Sometimes it is just because something basic isn't clicking for them, but a lot of the time it's down to me trying to explain things through a prism of accumulated patterns that are seen as best practise/common sense, but stepping back and viewing objectively are opaque and sometimes nonsensical outside of very specific scenarios. There's a tendency to massively overcomplicate, but you forget very quickly how complicated, then you build further patterns to deal with the complexity, ad infinitum

Yep the biggest issue we have with software is every developer knows Single Responsibility Principle, and no developers know why. Everyone knows decouple and increase cohesion, but few any know what cohesion is.
