"...but if droids could 'think'--none of us would be here." Greedy people that intentially make machines specifically designed to lower a companies expenses and raise productivity should be hospitalized. With unemployment comes an increase in crime and yet, somehow, they continue to see it as an 'advancement'. The amount of jobs that cannot be replaced by machines are so low that there will NOT be enough jobs all the time.

Personal perspective, people need to cut back on reproducing. There are too many humans, trying too hard to build wealth and abusing the resources that the earth can offer. The late great Carl Sagan explained this concept very well in his book Cosmos.

Look around you. The world is filled with inventions that have resulted in "job loss." The hand calculator eliminated the necessity for people to do calculations on paper. Steam shovels allow one man to move the same amount of earth as 5000 men. Mechanical weaving machines destroyed the jobs of thousands of weavers. Do new technologies cause some temporary involuntary unemployment? Yes. Do any of you honestly believe that humanity would be better off without modern technologies? I hope not. People used to have to work 18 hours a day, 7 days a week just to have bare necessities. New technology has lifted the standard of living all throughout history. It's the reason you have a computer in front of you and the reason you have the free time to contemplate such questions. Remember, the manual diggers and the weavers all found other work. There's ALWAYS other work to be done. If we could mass produce androids to do all the manual labor currently done by humans, the cost of necessities would fall through the floor and anyone doing manual labor for a living would be out of work. What would they do? Whatever is available. But rest assured that the amount of time a person would have to devote to work in order to sustain himself would be dramatically decreased. If you could live like you live now and only have to work a 20 hour week instead of a 40 hour week, would you call that an awful situation? I didn't think so.
