>biggest problem with smartphones

Disattention is happening because the user isn't actually in control of the smartphone, the smartphone is in control of the user, because that control is a commodity upon which a grand economy has been built. That control is only possible because the smartphone itself represents an extraordinary degree of managed control in the way it works, a fact which is used to obviate the users own agency over the product they supposedly own.

So I think the biggest problem with smartphones is that significant parts of the smartphone product no longer belong to the user, but they are in fact rented and leased out to other third parties for the exclusive use of attention-gathering.

We wouldn't have third party applications stealing our social media property as individuals - indeed they wouldn't be necessary anyway, in a functioning operating system - if the operating system of the smartphone was designed to make the user able to do social media without requiring a third party.

But smartphones are, literally, sanctuaries for third party economics, against a captive user. They have been designed, as such. Third-party social media is necessary because the operating system vendors are no longer designing operating systems for the users - but for themselves, and others, for which they are handsomely rewarded ..
