The Busy Worker’s Handbook to the Apocalypse

Has anyone read "The Busy Worker’s Handbook to the Apocalypse"? The document/post is available here.

What are your thoughts on it? If you just look at the conclusion, it sounds doomy, however, if you read the whole thing, it seems to be based on facts. I haven't read the whole thing, I skimmed through it though.

I am interested in hearing your thoughts.
