Tonight I made the mistake of watching one of the live streams replaying the first human exploration of the Moon in real time. The moment itself, of course, remains momentus even 50 years on; but I'm deeply saddened by the ignorance displayed in the commentary stream, where it seems perhaps 40 or 50 percent of people have signed on simply to decry one of humanity's greatest achievements as a hoax.
Some days I weep for us all.
