So yesterday I found the book version. And while it has plenty to think over, the presentation is iffy. Long before xkcd I'd decided that sciences/computers > liberal arts. The ideal Maslow-actualized techie would be baffled by This Is Water. Imagine how Spock or Sherlock or Sheldon Cooper would react to this.
I get what Wallace is saying, and he says it well. But I learned this existential stuff from Greg Egan, Bertrand Russell, Sagan, Heinlein, Asimov. You know, real nerds. Yes, I'm a science fiction snob too.
