"In today’s developed countries, nearly everybody used to farm the land, now almost nobody does. In the place of agriculture, we went to work in factories. Now, in the place of factories, we’re blogging, writing software, playing sports, designing web sites—a plethora of new jobs to keep ourselves occupied and pay the bills."
OK, so maybe not everybody, but to paraphrase William Gibson - the future's here, it's just not evenly distributed.
The point is that factory work (including most cubicle office work) and increasingly even many professional jobs are about to go the way of the farm worker.
Creativity, making original stuff and human connection are becoming the ingredients for most of us to make a living, and/or make an impact.
