In the past there were machines such as the Acorn, Altair, Amiga, Apple and Atari (in alphabetical order) that were designed to satisfy the personal computing interests of hobbyists, experimenters, children, learners and other home users. Over time the original idea of personal computing was replaced by play stations, xboxes and cheaper versions of the office computers used in work settings.
Recently a new machine called the Pi was introduced to bring the experience of personal computing back into the home. The size of this home market, which had gone unnoticed for so long by the larger companies, turned out to be surprisingly larger than expected. Millions of Pi computers are sold each year.
Originally, it was planned that RISCOS would be the main operating system for the Pi. This makes sense because RISCOS was specifically designed for the home market and the Pi was intended to satisfy people's personal computing interests. As we all know, Linux in the form of Raspbian turned out to be the main operating system.
However, Linux is a copy of Unix and Unix was designed to be a multiuser programming and document preparation environment at one of the largest corporations in the world. The likelihood of such an operating system bringing the fun of personal computing back into the home seems zero; however, to a large extent it has worked. Even so, a significant number of questions on this forum arise due to the fact that Linux is a complicated multiuser server operating system.
If one wants guidance from the past how to improve the current personal computing experience on the Pi, it makes sense to look at the operating systems which ran on the personal computers of the past. Unfortunately that past is long ago and it is easy to get so distracted by differences in the hardware as to lose sight of crucial differences in operating system design related to how and by whom the computer was intended to be used. Oh well, it's also worth remembering that Linux started out as a hobby operating system written by a single student for their personal use.
