Actually, he got the basics from his college textbook, which had Minix, itself a UNIX clone written from scratch by professor Andrew Tanenbaum, a friend of the creators of UNIX.
So, LUNIX is a rip-off of a rip-off, then. Very good, since Windows is a rip-off of a rip-off too. Except it doesn't suck as bad as LUNIX. Except for all the viruses and malware the jealous LUNIX geeks write it's a hardly noticeable level of suckiness.
But, realistically, I don't think there will ever be an O/S that doesn't suck, it's the nature of the machines. Maybe, one day, if there are organic computers that write their own O/S based on their biological function, that might be as close to zero suckiness as it can get, but it's probably a long way off if it happens at all.
