It's possible* to build a software which understands natural human language and allows for vague, abstract expressions. Sometimes communication fails, which is why different "commands" should have different risk levels and different degrees of formality. For example, if I order pizza, I can be pretty vague, but when I order clothes online, I need to specify the size, color etc. more formally. * It's possible since you can always simulate a human brain with software, but there are of course more practical artifical general intelligence systems like the AIXI-mc.
