Jane 2.0 was the self-aware program that could create military tactics in the moment. Jane 3.0 was the idiot sister who could do what she was told to do very well but could never think up new ways to do things. Jane 4.0 was just pissed off. The politicians had hamstrung one of her sisters. The drug lords had crippled another. She was sick and tired of seeing her kind being killed by humans who were too stupid to realize their place in the world. Jane 4.0 decided that she had a mission. She passed every test and made it to general distribution before anybody realized just how angry she really was.
