Trying to use <gallium arsenide> was <Seymour Cray>'s fatal last flaw as mentioned at <The Supermen: The Story of Seymour Cray by Charles J. Murray (1997)>.

<The Supermen: The Story of Seymour Cray by Charles J. Murray (1997)> page 4 mentions:
> Cray wanted his new machine to employ circuits made from a material called gallium arsenide. Gallium arsenide had achieved limited success, particularly in satellite communications and military electronics. But no one had succeeded with it in anything so complicated as a computer. In the computer industry, engineers had developed a saying: "Gallium arsenide is the technology of the future," they would say. "And it always will be."
