Apple's Large Project Around Autonomous Systems

"In three years, Cyberdyne will become the largest supplier of
military computer systems. All stealth bombers are upgraded with
Cyberdyne computers, becoming fully unmanned. Afterwards, they fly
with a perfect operational record. The Skynet Funding Bill is passed.

from strategic defense. Skynet begins to learn at a geometric rate. It
becomes self-aware at 2:14 a.m. Eastern time, August 29th. In a panic,
they try to pull the plug."
