They also have destroyed humanity's ability to socialize like nothing else.
Hah yeah, it's quite terrible.
I've seen entire families at McDonald's not talk to each other, they were just staring at their phones.
I wonder what the future's going to be like if this trend keeps up.
It will keep up. Human beings have a tendency to drift towards what is convenient and easily entertaining. Smart phones, tablets, smart watches, and whatever other personal technology devices will reach mass adoption are convenient and easily entertaining. We won't give them up anytime soon. Only those that are consciously aware of this behavior will overcome it, and the percentage of us that are consciously aware is certainly not in the majority.
I don't think this is true.
Nearly everyone has woken up to tablets and phones being basically useless.. and the pc is much better for media consumption.
The only people using their phones/tablets heavily are doing it as a primary source, they don't own a very good pc, and so the phone and tablet is their best media outlet.
