Plan9 is not that successful and not a good representation of actual Unix use. Doesn't GNU Emacs run on Plan 9? Wait, there is Acme. What about Acme's architecture? > Acme is about 8,000 lines of code in Alef, a concurrent object-oriented language syntactically similar to C [Alef]. Acme’s structure is a set of communicating processes in a single address space. One subset of the processes drives the display and user interface, maintaining the windows; other processes forward mouse and keyboard activity and implement the file server interface for external programs. The language and design worked out well; as explained elsewhere [Pike89, Gans93, Reppy93], user interfaces built with concurrent systems can avoid the clumsy top-level event loop typical of traditional interactive systems. That does not sound like Unix philosophy. Communicating processes in a single address space application. On Plan 9. Written by Rob Pike at Bell Labs. We've seen companies like SUN, IBM, HP, DEC/Compaq/whatever they are called now/..., etc. earning zillions on big fat applications. Big fat GUI applications and big fat server applications. From any Oracle DB, to any Java application, to basically every desktop application - none follows the so-called 'UNIX philosophy'. Thus tools like GNU Emacs have zillions of similar applications under UNIX and GNU Emacs is nothing special at all.
