Not the most flattering of nicknames, the Strang Institute’s main computer CPU, the Egghead 2000, received that handle back in the days when the number 2000 was meant to mean something was futuristic. The egghead part was meant as a bit of a joke that unfortunately stuck.
Built in the 1960s, unlike most of its contemporary supercomputers the EH2000 didn’t become obsolete. That’s because it works like a human brain, constantly learning and growing, using technological secrets that the Institute keeps closely guarded (my security clearance doesn’t allow me access to that information).
Ellie’s central processing unit uses similar technology.
