A debate unfolded on X around LessWrong's "pivotal act" concept. jessicata pressed on what a "melt all GPUs" pivotal act would actually entail: the military holds GPUs in highly secured locations, and in theory diamondoid nanobots could disassemble them without killing anyone — but that would mean independent force projection slicing through existing defenses.

NathanpmYoung pushed back that this isn't what's proposed and Yudkowsky would oppose it: unilateralism damages trust, a resource alignment needs. The post links LessWrong's definition of a pivotal act as an action decisively settling the gameboard for the better over cosmic timescales.
