I cannot disagree at all with this statement however I ask what about those connected devices that have no displays but still exist in our world "unseen"?

Take for example the Kohler poo cam announced a few weeks back that has no screen but maybe they secretly included a small speaker that after a firmware update will plop ads on bowl users if management is not seeing the profits from selling only the hardware. Won't that be some funny sh!t?

Or how about brain implant computers, so I ask where will the line be drawn when more and more profit at any cost appears to be the M.O.

Exciting times as connected technology that can see and hear gets smaller and smaller while battery power to weight ratio increases allowing these devices longer and longer life in secluded places.

Ads are 'yesterday' on my screens and it's always been thus, and it will always be so.

Your premise will only become true if people on mass agree with it.

Why stop there ? You can display it directly in the brain.
