I watch a lot of How It's Made. On many episodes you'll see an assembly line that is almost entirely automated, except for some small section. Sometimes that section involves (A) precision work that we haven't yet figured out how to automate. Most other times it seems to be (B) extremely "automatable" work (e.g. grabbing widgets six at a time and putting them in a package) that leaves me scratching my head as to why the robots aren't there as well.<p>I watch these episodes and think to myself that these workers are just the last portion of the line to be replaced by robots, and it's only a matter of time, capital, or both. Demos like this move the line between (A) and (B). The Industrial Revolution was only a half-step--just the "brawn" part. Now we're in the middle of the "brains" part, and the outcome is both exciting and scary.
