There's something that particularly bothers me about Goodfellow's article. He condescends about crazy theories while making ridiculous assumption after ridiculous assumption while acting very authoritative about each one. Just because his theory is less "sexy" (it doesn't involve hijacking or terrorists or suicide) doesn't make it any more valid. I'm appreciative of commentary that urges a more prudent approach, not a condescending and equally implausible theory that happens to be boring.
