Word documents will be saved to the cloud automatically on Windows going forward

More than anything, Microsoft is incompetent at messaging and communications.

This is a feature that has been among the most loved aspects of its main competitor for more than a decade.

Somehow, Microsoft managed to make the same feature sound and feel and be creepy.

OneDrive has to manage synchronising the cloud with multiple, potentially independently updated, local copies. This is a much harder problem than anything Google have tried to tackle, with more ways for things to go wrong compared to "no internet connectivity? No documents for you!"

This has the effect that (to a first approximation) everyone knows someone with a horrific OneDrive data loss story, no-one particularly trusts OneDrive with anything actually important, and so no-one wants to be forced to use it for everything.
