"He also co-developed the Blit graphical terminal for Unix; before that he wrote the first window system for Unix in 1981. Pike is the sole inventor named in AT&T's US patent 4,555,775 or "backing store patent" that is part of the X graphic system protocol and one of the first software patents. [1]
Over the years Pike has written many text editors; sam and acme are the most well known and are still in active use and development.
Pike, with Brian Kernighan, is the co-author of The Practice of Programming and The Unix Programming Environment. With Ken Thompson he is the co-creator of UTF-8. Pike also developed lesser systems such as the vismon program for displaying images of faces of email authors."
Yeah, some amateur engineering right there. My point still stands; heuristically I have every reason to believe an extremely competent arquitect and designer who is involved in good faith on this project over a random commententer who can't be bothered to assess the evidence.
