I'm not sure I agree. A magic folder that syncs across all your devices is going to be useful for the foreseeable future. Eventually maybe Dropbox dies without real innovation but I think that fundamental concept could last for decades.

This is exactly why they must innovate. Their core tech is useful, but it is also replicable; so as soon as someone has magic folder PLUS more useful features bundled together (as some already do), Dropbox fails to be as worth having as a separate service for users that prefer the bundle. Which is why they have issues at present.
