Just a look at the posts on this forum re all the glitches in the airbnb app as compared to the desktop version tells me how "smart" these apps, etc, are in reality.
One thing I've experienced re smart phones is that they have affected call backs or text responses, because instead of there being "You have one missed call" across the screen of my old school dumb cell phone, these so called smart phones have some tiny notification symbol in the corner, which people just don't bother looking at half the time. Then I get "Oh, sorry, I didn't notice your missed call" (from 3 days previous).
People have gotten seriously lost on road trips, sometimes ending up in the middle of nowhere in the desert when folllowing GPS instructions.
What are supposed to be time savers end up taking inordinate and frustrating amounts of time to resolve when they glitch out or cease functioning. People are being propagandized by the manufacturers of these products that they are the best thing since sliced bread, and that they are must-haves in todays world. Nothing smart in my house except me 🙂
