Of course, any philosophical zombie could have invented it. Which makes clear for me how loosely consciousness is bound to senses, including that of introspection. It actually makes me feel that this consciousness we can barely describe is but a faint experience of a distant, largely foreign thing. Like we know the experience of matter that we get from our senses is a grossly simplified version of the real thing (that we still don't know exactly of course, but we already know enough to see how far away our immediate mental model is from the truth)
