Likewise, we can replace certain kinds of thinking work (e.g. programming or medicine) and that in itself isn't a major problem (except for the out-of-work programmers or doctors).
But replacing all cognitive activity (which is what a hypothetical future AI would do), what are we --- as humans --- left with?
