Horselover, I just like to ask you something.
According to this, the US has a projected population of 305 million people.
The super-rich accounts for only 0.9% since 2005 though.
That's only 2,745,000 super-rich people, while there is 302,255,000 non super-rich people.
Now, take a away...let's say a third of both statistics to account for children.
1,830,000 super-rich adult people are left, while 201,503,333 adult non-super rich people are left.
Now, don't forget that police and soldiers are in the latter category.
So, what you're saying is that the government will have no problem with robots policing us and fighting for us? How will robots react if they see civilians? Surrendering soldiers? Crazed criminals? Hostages? There's too many variables. Plus, there's a chance the family of those police and soldiers will be protesting (or rioting), and the police may not have a problem with using a non-lethal weapon, how are the soldiers suppose to use their weapons on the civilian populace? Who all just want to have income equality? And what about their family and friends, what would happen if they riot?
I know this isn't a bulletproof post, but I just wanted to point that out.
