If we stay the same we know what to expect. We know how we will be attacked and from where and usually by whom. If we advance, mature, evolve, and/or change we may stir-up the soils to discover new adversaries, new treats, new ailments, new risks and hardships. So, why would we ever choose to go from the known to the unknown? The answer is simple, survival.
Not too long ago in human history groups of people would build dirt barriers around their living areas for protection. This lasted a while until some explorers met people with horses and decided horses were a convenient means of travel and attack. The people changed and the defenses needed to change in response. Sometime after that people learned that throwing rocks through and over the dirt was an effective attack tool as seen in other geographical locations. Once again, the change was forced by the outside factors. At some point great stone castles were erected for protection and the people changed. It may have been during this period that social strife created conditions that were so deplorable tha religious persecution, torture, slavery (via indentured servitude), slavery (as known in modern terms), and other atrocities caused people to flee to a new world. This time, using geographic dispersion to claim safety. Not long after electricity and electric means of communication were born. People changed. Then came the computer from the mainframes of academia to the servers of national intelligence, advertising industry, and economic prediction and management data super-centers. Every keystroke, every camera, every microphone, every device a means to track, manage, extort, and monetize all humans. How will humanity change?
