Is that not the point of his remark? As I understand him, he's implying that Larry Wall is the only one who knows more about language design than Rob Pike and Chris Lattner. Therefore, we should listen to Rob and Chris.

Or maybe it's your comment I'm misunderstanding?

Edit: Ah. It's been pointed out that perhaps your own remark about Larry Wall was intended as sarcasm (or, equivalently, was intended as a paraphrasing of the quote above it). So it's probably the latter.
