> Depending upon your priorities, your ethical views will inevitably be incompatible with those of some other people in a manner no amount of reasoning will resolve. Believers in a strong central state will find little common ground with libertarians; advocates of radical redistribution will never agree with defenders of private property; relativists won’t suddenly persuade religious fundamentalists that they’re being silly. Who, then, gets to say what an optimal balance between privacy and security looks like — or what’s meant by a socially beneficial purpose? And if we can’t agree on this among ourselves, how can we teach a machine to embody “human” values?

Those who build the machine will embody it "their" ethical values. Problem solved.
