Hopefully it isn't intentional to suggest that you need to be a genius "guy" to do this. To be fair, this is about where I closed the article so maybe I missed the point.
It's entirely orthogonal, but the other half of that, the implication you have to be a “genius” to write a compiler, also annoys me. Is it really rocket science?
(I suppose it depends on what “real” means, though.)
