All joking aside, I fail to see anything wrong with this at all. I think it's kind of stupid that every time we see an advancement in robotics, people immediatly jump on leftist technophobic fiction about how the machines will try and replace, imprison, or kill us.
On a more practical level, my issue with this technology is more along the lines of society not being ready for it. Right now we're already dealing with the issue of a society so advanced that we have no need of the workforce we have, one of the big issues causing economic problems today. With the right equipment you have one guy doing a job that might have taken ten or twenty guys. This is one of the major contributing factors to things like layoffs, which of course leads to unemployment and a lot of our economic woes. This is not the only issue here, but it's a big one.
This kind of a technology hitting the market is liable to see it replacing human labour on a massive scale. It would be fine if we were in the midst of massive inter-steller expansion or whatever with humanity spread out all over the place, but right now it's a recipe for self destruction with workers being knocked out of work, destroying the markets, and then leading to the demise of the businesses themselves with nobody to buy products. I'm not going to go off on an economic rant, since there are various theories (both agreeing and disagreeing with me) and on these forums I figure most will have read plenty of dark future fiction to get the idea.
I don't much like big goverment regulation of well... most things, but I think this is technology that should be kept entirely in the hands of specific goverment agencies like the Space Program, and made illegal for civilian and private market use. I also tend to think that it's one of those cases where certain nations are liable to decide not to ban it to get a leg up on more powerful nations that do. This might very well result in a global war because honestly I think it's one of those jingoistic situations where wearing a "world police" hat is probably for the best. Besides a global war is actually a good thing since getting rid of about 80% of the global population and then surpressing a baby boom would benefit everyone that survives (like it or not). I figure it's inevitably going to happen over tech or intellectual properties/patents/copyrights anyway, and if things snowball here it's as good a place to throw down as any.
Of course I'm thinking well ahead of the situation here, we'll see what happens. Good tech, but ironically one where the benefits are liable to do more damage than anything.
