I moved this to COFF since it's a TWENEX topic.  Chet Ramsey pointed folks at a wonderful set of memories from Dan Murphy WRT to the development of TENEX and later become TOPS-20.   But one comment caught me as particularly wise and should be understood and digested by all:

"... a complex, complicated design for some facility in a software or hardware product is usually not an indication of great skill and maturity on the part of the designer. Rather, it is typically evidence of lack of maturity, lack of insight, lack of understanding of the costs of complexity, and failure to see the problem in its larger context."
