OS designers decided it was too hard to educate their users and that they couldn't compete with the marketing people, so had to find a way to build 'value' and 'earned revenue' with their Operating System plans. So .. They dumbed-down the filesystem so they wouldn't have to explain it any more. And then they decided to never fix Finder/Explorer ever again .. and then they tried to get rid of it altogether. And even still today there are people who cannot understand the difference between a file and a folder, nor where or how they should organize their personal data in a way that makes sense. OS vendors decided to exploit this stupidity through anti-patterns that gave their bosses (the Marketing People) access to millions of users data... The OS vendors dumbed down the user interface to make it more appealing to look at every day for hours and hours .. and then they forced us to watch ads in that interface. They forgot that computers are general purpose devices, and tried to make us only do a few things with them. They removed the compiler. They removed the compiler. <-- this is the most significant point at which personal computing went wrong. Instead of building a better compiler and a nicer machine to use, the OS vendors decided to make money off their developers, instead. OS vendors stopped vending operating systems and became Marketing People™,®,© instead .. Meanwhile, users get away with still not knowing what a filesystem is .. or why it matters to have a copy of that data out in the cloud, or locally on a machine in a place they can easily find it. The fact that this is still such a huge conundrum means that there really aren't any good computer operating system people out there any more. They all went off to work for a FAANG and promptly retired.
