How I hated UNIX back in the seventies - that devilish accumulator of data trash, obscurer of function, enemy of the user! If anyone had told me back then that getting back to embarrassingly primitive UNIX would be the great hope and investment obsession of the year 2000, merely because it's name was changed to LINUX and its source code was opened up again, I never would have had the stomach or the heart to continue in computer science.
