Honestly? This goes further back to Gmail, Google Chrome, and the rise of the SaaS/PaaS era IMO. Who needs "software" and "files" when everything runs in the browser, right?
Hell, Chromebooks are exactly that unless you hack them, and despite everyone seeming to have forgotten about them, they're still a thing, still successful, and especially scarily, are being given to millions of students every year.
People complain "oh these kids with their iphones don't know how to use a filesystem" but our education system continues to give them fake net appliances instead of real computers to this day. Even the awful, locked down NT instances I grew up with were more computer than "your laptop is just Chrome now, better learn Google Docs."
