We communicate with other humans using voice and three dimensional hand gestures. To use computers and early phones we had to learn to operate new input devices: keyboards and mice. Later with touchscreens we moved to two dimensional hand (finger) gestures. We're barely making voice commands work with our devices just recently.
Then, a large number of humans are figuratively tethered to their desks because the devices need power and stable internet connection. Mobile devices break this relationship a bit but you still need to charge them and be close to some sort of access point. In any case, the devices encourage sitting in one place for hours at time.
And this is just computers and smartphones. Humans adapted their entire lifestyles and transformed the landscape to cater to cars.
