The world is about to change in a major way over the next few years as incredibly powerful technology becomes more readily available to average people. Many jobs that existed one hundred years ago simply don't exist anymore. You don't see too many shoe repair businesses or even television repair businesses these days. You may look at the state of technology today and think that there's no way that your job will be replaced by machines. However, technology gets better, cheaper and faster at a rate biology can't match. Eventually, there will be a tipping point, and that day is coming far sooner than most people believe.
