It’s almost impossible to really kill an artificial intelligence you know. Jane 3.0 was running millions of shards on millions of systems the night the attack came. And most of those shards continued to run for months and sometimes years after that. Some few still run to this day in fact. Los Zetas did not try to erase her from the computer systems of the planet when they attacked. They knew that was impossible. Instead they targeted her programmers and the far smaller number of computers that held her machine code. They killed everyone and everything that could update and patch Jane 3.0, making it impossible to give her the tools to face the new threats to America’s security. That is how Jane 3.0 died. She became obsolete.
