The "value of a human" - same in this age as it has always been - is our ability to be truly original and to think outside the box. (That's also what makes us actually quite smart, and what makes current cutting-edge "AI" actually quite dumb).

AI is incapable of producing anything that's not basically a statistical average of its inputs. You'll never get an AI Da Vinci, Einstein, Kant, Pythagoras, Tolstoy, Kubrick, Mozart, Gaudi, Buddha, nor (most ironically?) Turing. Just to name a few historical humans whose respective contributions to the world are greater than the sum of the world's respective contributions to them.
