The Lisp Machine is a product of the efforts of many people too numerous to list here and of the former unique unbureaucratic, free-wheeling and cooperative environment of the M.I.T. Artificial Intelligence Laboratory. I believe that the commercialization of computer software has harmed the spirit which enabled such systems to be developed. Now I am attempting to build a software-sharing movement to revive that spirit from near oblivion.
Since January 1984 I have been working primarily on the development of GNU, a complete Unix-compatible software system for standard hardware architectures, to be shared freely with everyone just like EMACS. This will enable people to use computers and be good neighbors legally (a good neighbor allows his neighbors to copy any generally useful software he has a copy of). This project has inspired a growing movement of enthusiastic supporters. Just recently the first free portable C compiler compiled itself. If you would like to contribute to GNU, write to me at the address above. Restrain social decay–help get programmers sharing again
