Communication is one. When I was starting to date, land lines were it and a lot of phones still had dials. Parents limited phome time and the number of calls because no one had answering machines and caller ID and call waiting hadn't been invented yet. So if you were on the phone and someone called they got a busy signal and there was no way to know that a call had been missed. The idea of being in constant touch, on a phone that went everywhere with you and could take pictures was the stuff of futuristic TV or movies. Are cell phones bringing people closer or smothering them?
Porn is another hot topic that technology has really increased access to it. 20 years ago the idea of being porn addicted was pretty limited. It's gone from drawings or live shows to film in a theater to video to online. It's also gone from being very much a male thing to more and more women watching.
There are probably dozens of other things. What do you think?
