All of Braid, The Witness, and Order of the Sinking Star are excellent video games. Granted, that's 3 pieces of software over about 20 years (as well as his programming language, which is perhaps interesting but still unfinished and unproven), but it's still the case that Blow has actually produced valuable software artifacts I am happy to have paid money for. This isn't to say that his opinions about software are necessarily correct, especially software that isn't similar to video games; but I don't think it's fair to say that he's accomplished nothing comparable to what he talks about.
