It isn’t clear he was always right. One trend he bucked was to use address translation, including paging because it introduced another memory lookup for every memory access. This made the porting of UNIX to the Cray 1 a very difficult task.
In general he moved from project to project, often before completing the last. Les Davis is often credited of finishing his designs and making them work. He had no Les Davis at Cray Computer.
He went against conventional wisdom of using VLSI, CMOS by sticking with GaAs without industry’s support. This may have contributed to his lack of success in the 90s with the Cray 3 and 4. All of the technology was unique.
