Earlier quoted context omitted.
You can already see it in people who cannot navigate their automobile without google maps or some equivalent.
Define "cannot navigate"? I've been driving for decades, but where I live traffic is everywhere so I don't go more than a few miles without using Waze and its real-time traffic monitoring.
Normally, I just glance at what action I should take next (i.e. continue straight for 2km and then take a left turn at X) and then follow the road signs to do so. But I've noticed some Uber drivers and other people who keep their eyes almost permanently at the app for locating themselves, even when there's a clear GPS or network disconnection, like in an underground pass. This often results in wasted time when the app doesn’t catch up with reality, and the driver misses a turn.
