<Unix was just a small hack inspired by Multics, and looking at contemporar <operating systems, I'd say there were some that were way ahead of Unix (an <still are...) yes, but as hacks go it was more public in code than other OSs of value in that time frame. I'm not saying was the best. Also I've never used multics. My experience in chronological order is OS/8, TOPS-10, CP/M-80, NS*dos<z80>, RT-11, RSTS, RSX-11, VMS, Ultrix. So those are what I have to look at when thinking in terms of 1970s OSs like Unix of the time. <Operating systems in the last twenty years have really retro-developed. :- If you mean what I think the answer is not here. If anything my view is more of when will dos/winders perform as well as some of those OSs of the time. Then again, I had VMS4.6 running decwindows and four users on a microvaxII with 9meg and 3 RD53s in 1989.
