Make no mistake: We're still probably at least a decade away from any kind of meaningful shift away from the smartphone. (And if we're all cyborgs by 2027, I'll happily eat my words. Assuming we're still eating at all, I guess.)

Yet, piece by piece, the groundwork for the eventual demise of the smartphone is being laid by Elon Musk, Microsoft, Facebook, Amazon, and a countless number of startups that still have a part to play.

And, let me tell you: If and when the smartphone does die, that's when things are going to get really weird for everybody. Not just in terms of individual products but in terms of how we actually live our everyday lives and maybe our humanity itself.
