For me the connection with hacking is that it points out a potentially unintuitive thing, and switching from hunting to agriculture also is a kind of hack. Is a startup not also trying to hack society in a way? Also I thought it interesting that some ancient societies seemed to have less work hours.

Obviously it won't interest everybody, but didn't pg say "anything that interests hackers", not only hacking itself?

Anyway, my apologies if it was too far stretched. I hope I will refrain from further submissions in the future. Perhaps I should check out Reddit...
