My hypothesis is today's "modern" OS user interfaces are objectively worse from a usability perspective, obfuscating key functionality behind layers of confusing menus.
It reminds me of these "OS popularity since the 70s" time lapse views:

The dominance of Windows is crazy, even today, Mac desktops and laptops are comparatively niche
There was no one who could help me when I got stuck, beyond maybe an instruction manual. I just had to figure it out, mostly by trial and error. I learned so much, eventually being able to replace hardware, install and upgrade drivers, re-install the entire OS and partition the hard drive, figure out networking and filesystems. It built confidence.
Now my kid sits infront of an OS (Windows, Mac, it doesn't really matter) and there's so much noise. Things popping up, demanding attention. Scary looking warnings. So much choice. There's so many ways to do simple things. Actions buried deep within menus. They have no hope of building up a mental model or understanding how the OS connects them to the foundations of computing.
Even I'm mostly lost now if there's a problem. I need to search the internet, find a useful source, filter out the things that are similar to my problem but not the same. It isn't rewarding any more, it's frustrating. How is a young child meant to navigate that by themselves?
This looks like a step in the right direction. I look forward to testing it out.
