Those same people might say that it is just the experience of "being the computer" rather than seeing it from afar. But I don't know, because personally it isn't an argument I find convincing.
As an aside, I think you have to be a bit arrogant or closed minded to assert that they actually can see the problem. I really don't think my wife is lying or being nefarious when she says she doesn't see a problem. I trust her and others when they say they don't see a problem.
