Humans beings can be divided into two classes. The exploiters and the exploited. Exploiters are constantly looking on ways to do more efficient exploitation. So every new technological "thing" that get discovered, will be considered by the exploiters to do more efficient exploitation.

So every thing, even if this thing have huge potential to do good, will eventually be discovered by the exploiters to do more efficient exploitation. I will go even further and will say that things that does not aid much with efficient exploitation won't attain wide spread usage in this day.

For example, we got a TV in each home, becuause that would help with more efficient exploitation. Each of us have a full color, slab like smart phones with a dozen listening devices with 24x7 internet connection because, yea you guessed, it, because it helps exploitors to squeeze that last drop of juice out of you...

Now I am not saying that there is a self declared bunch of exploitrers that decides which tech should go mainstream, but I think this is sort of emergent behavior, given the primal instincts in each and every one of us human beings..
