> I believe you're underestimating just how poor the "average user"s understanding is of what's going on in "their" computers... they literally have no concept of "where" their photos/email/etc. is stored or backed up: in the cloud, on device, synchronised,... it's just a single black box. They literally have NO mental model of that. It's probably something that should be taught in schools, early-on, when people have the neurological flexibility to absorb it. Sure, the technology will change after you get out of school, but I'm pretty damn old, and filesystems and the client/server model haven't changed a whole lot since I was in middle school. When I was in school, they didn't really have computer classes, and I think the generation after me basically got "how to use Microsoft Word", when what we all really needed was education in the fundamentals.
