Check out the 100% cotton Superman Kryptonite Element T-Shirt but don't breath too deeply...I think with an atomic weight that high there may be some ionizing radiation that can prove to be deadly for native-born Kryptonians! I think we'll be alright though...I don't think a rogue AI has ever altered our birthing matrix or at least as far as I am aware. Perhaps if you have the Superman Kryptonite Element T-Shirt you can run around going 'SUPERMAN, &#$%^!' I'm thinking of a 'Breaking Bad' reference with that previous statement.
