Oh come on... this man worked and prepared for this for 5 years and the way I understand it, there were definitely some uncertainties about how his body would take it; black out, red out, burst arteries etc. so even in the case of all parts working as intended and a safe landing he was in enough danger. A lot of preparation and a lot of technology went into this.
Why belittle it like that? Just because it did not immediately bring humanity forward a gigantic leap? You could argue the same about music, heck Mozart's and Bach's works are just soundwaves and the same frequencies have been tested very thoroughly, they propagate through air and water just fine! All sorts of colours can be found in nature, why draw a painting? No need to test whether our eyes can perceive colours on a canvas!
I am sorry, Mr. deGrasse Tyson, but humans are more than just efficient, self-improving robots and our most human moments were and are to be found in play and in otherwise completely "useless" activities like art, music, sports or record-chasing which do nothing but making us and maybe others feel good or thrilled and captivating people's attention for a moment.
