From a Friedman perspective, electronics are what flattens the world, under the category of "steroids". The reasoning of steroids is because essentially, everything is made simple.
Today with a smartphone, everything is at your fingertips, literally! In the palm of your hand and just a click on a glass screen away, you can have; messages, emails, phone, music, social networking, and for some most importantly games.
Way back when in the late 1990s and early 2000s, a cell phone was only used for calling. (I know right?) But now people like Steve Jobs and Bill Gates created something so much more. Because of what those geniuses created we now have today a very competitive franchise of smartphones coming from companies like; Samsung, Apple, Nokia, and Windows.
It is amazing how much phones have evolved today.
