A text editor is user-facing; the underlying filesystem hierarchy mostly isn't. I'll grant some of it is; it would make sense for a user to know (and perhaps even care) about /home, and in a system that isn't centered around a package manager I could even see them caring about whatever the directory is for applications, but beyond that it doesn't matter how /usr is laid out, or how the CPU is microcoded, or whether the kernel is monolithic, or whether their applications are written in Rust or C#. It's a black box, and for less-technical users that's fine. I won't say there aren't ways to improve, even to simplify things, and I do wish that normal people still programmed, but the reality is that computers really are just that complicated, and once we get over trying to explain technical things to less-technical people, the FHS is fine for what it is.
