Reminds me of Linus Torvalds. He works on top of a kernel he has (initially) written himself, using a VCS he has (initially) written himself, and using an ancient heavily-customized editor [0,1]. Somehow his tools are more successful than Pike's. However, I doubt we could convince Torvalds to create a programming language.
