In a 2016 engineer
employee profile about Hall, it reads: "Isaiah is fascinated by artificial intelligence and believes that 'the Singularity is going to happen. In fact, it's highly likely within the coming decade.'"
Hall's life disturbingly mirrors some of the members of the "
Zizian" transgender death cult, whose geeky vegan members were mostly engineers obsessed with the idea of "the Singularity" before becoming allegedly homicidal and suicidal.
"The Singularity" concept claims there is a point in the near future where artificial intelligence surpasses human intelligence and can pose immense and catastrophic danger. The "Ziz" cult members, who hail from across the U.S. and Europe, cut off ties with their families to debate these ideas endlessly. Most of them became homeless, also living in a white van like Hall, and allegedly killed at least six people, in accordance with their beliefs.
There is no other evidence so far to suggest Hall was a member or associate of the group, however, despite their disturbing biographical and deep interest parallels.
Catherine, who had not heard of the Zizians before the interview, says she vividly remembers her ex-husband being heavily focused on "the singularity."
"He explained that AI was going to be sentient, 'the singularity' was going to happen, and that we were all doomed," she recalled. "He was paranoid about it."
