You have to remember this is a site geared towards American techbros. Americans don't know what culture even means, much less why it's important. Cultural creations to Americans are shit like burger or Coke ads.
It's even worse for techbros. All techbros ever read are self-help books and Nick Land's meth-fueled ramblings. Peter Thiel is a head honcho techbro because he was able to finish The Lord of the Rings.
