Ewald runs Cray into ground. Silicon Graphics doesn't can him, he hangs around building political power, and proceeds to play a key role in running SGI into the ground. SGI barely (maybe) recovers, and Ewald, like a very bad penny, gets another try.

Maybe buy another house for him this time?

Bringing Ewald back as CEO should be due cause for the removal of the entire board. Alas, accountability in the Valley died a long time ago.
