So is Unix. ;-)

Note that the book (in which the preface is wrong: Unix was designed for the PDP-7, not for the PDP-11...) is from 1994, so things have changed a lot. Lisp machines are still around (at least GNU Emacs which is a virtualized Lisp machine is) - and the largest group of today's Unix haters are probably Linux users as Linux is deliberately violating many of Unix's principles (and has gradually been killing every effort to improve Unix; I would even conclude that the rise of Linux has left Plan 9 to rot).
