When we create technology we're creating bigger levers. Levers amplify our motions and all other tech does the same. Computers amplify our ability to calculate, communicate and create. Telescopes allow us to see further, cars; travel faster and sunglasses; look cooler.
You get the point.
It amplifies the good and the bad in us, worst of all the stupid. Be careful out there our levers are getting bigger and more powerful and it's really easy to smack someone in the back of the head when you forget how long your lever is.
