Good question. Author is incredibly hostile to one of the most important pieces of software ever developed because of the way they approached the problem nearly 40 years ago. Then he criticizes Go for trying to redesign the system instead of just using target triples...
The author writes: "really stupid way in which GCC does cross compiling [...] Nobody with a brain does this [...]", and then admits in the footnote, "I’m not sure why GCC does this".
Immature to the point of alienating.
