Great points, but I'm still the weirdo without the phone.
I'm old-fashioned, and rather than ignore everyone around me, I still try to believe in striking up conversations with people - that's the way it used to be. People here have heard me rant about the dog park, and how all the drones walk around with their face buried in their phones rather than meeting people in the park.
I think there are a few that can multi-task, but not the majority. Tests show being on the phone texting is just like having had several shots of alcohol, and reaction time is diminished. Also, I have seen way too many YouTube videos showing texting people walk out into traffic, fall in holes, walk into things, and lets not forget kill people while texting and driving. I used to teach teens/young adults, and I can guarantee you there was no multi-tasking going on there!
It may be the wave of the future, but I look at it as devolving, not evolving. I guess only time will tell, but I don't like what I am seeing.
Regarding the alien show, I would think if they were locked in 24 hours a day, there would be more communication, not less, as they were a captive audience and what else would there be to do?
