Nobody wants their data on their own device. Nobody knows how their devices even work, let alone wants the responsibility of managing them.

What they want is what they're (sorta, kinda) being given. My device takes my data and puts it somewhere where all my other devices know how to get it. I don't wanna know how it happens, I just want magic.

We, who know how our devices work, and don't want anyone else managing our data for us, are in a vanishingly small minority.

The big companies are putting their money on clouds and centralization. And that's where it'll all go, because they have all the leverage. Twenty years from now, I'd love to reflect on how wrong I was to say this. But right now, I doubt it.
