He seemed to have said: "I worked entirely on Plan 9, which I still believe does a pretty good job of solving those fundamental problems."
I would like to hear what exactly was done better in Plan 9 in regards to IPC. If I recall correctly Plan 9 is open source now - is there more development going on now or is it stalled?
There are forks which are undergoing active development like 9front, although I don't think anything from Bell Labs is still coming with respect to plan 9.
