Most of the points he makes are a byproduct of expecting too much from other people. I.E. gem authors, or misunderstanding why something exists I.E. the ruby standard library, which is a motley crew of modules meant to let people write hacky scripts a la perl. This is why I'm getting away from magic/cleverness as much as possible. Clever solutions usually rely on the dark corners of a language/ecosystem, which might break in the future.
