For example, have you ever used the system settings panel in Windows? It’s the most confusing, horrible, and neglected part of the OS. For like 15 years they had mashed together settings panels from different versions of Windows without even bothering to make them visually consistent. Ditto for a lot of Linux distros.
I think you’re overthinking it. MacOS has barely changed at all in last 20 years from a UI perspective compared to Windows. Upgrading from an 8 year old intel model to an M1/M2 model is going to feel like strapping on a jetpack.
