I think it was a bit too far ahead of its time. By the mid-1980s when I encountered it, it felt dated; the communications increasingly felt slow. Attempts at commercializing it, and on running it on newer hardware didn't really go very far. There were implementations of TUTOR for MS-DOS as well, with TenCORE being one that I saw. Early in my programming career, I came across it when we were rewriting a financial planner that was originally written in it into C. I was flabbergasted when my Lotus 1-2-3 importer was twenty times faster then the original. On reflection, I realized that TenCORE so completely imitated its CDC Cyber heritage that it used Cyber floating-point format for its math, and had to emulate every math operation.
