The first Mobil phone was created on April 3, 1973, by Martin Cooper, this was a turning point in the technological revolution because it made conversing with others long distance easy.
This first invention allowed more inventors to work off of this model making phones more user friendly and over all better.
Mobil phones became very popular, the need for them made them cheaper. Until almost everyone was apart of this new trend.
People have a natural desire to be better than the people around them, with that in mind, technology will expand to fill that need.
There are only so many versions of an iPhone creators can make, and when the internet can't get any better and Mobil phones people will get bored. As people get bored there is only more of a reason to come up with a new gadget to reengage the populations.
Another depression will occur, a technological depression. We will hit a point where there is nothing new and exciting to be founded or created because we would have seen it already. But that will be the time of the smartest minds fighting to be the savior of our lack in technology and be known as a hero.
