Part One: Earlier this year a Border Patrol officer was killed in a shoot-out with people who have been described as members of a trans vegan AI death cult. But who are the Zizians, really? Robert sits down with David Gborie to trace their development, from part of the Bay Area Rationalist subculture to killers. Part Two: Robert tells David Gborie about the early life of Ziz LaSota, a bright young girl from Alaska who came to the Bay Area with dreams of saving the cosmos or destroying it, all based on her obsession with Rationalist blogs and fanfic.
