Not having a hardware overhang makes your planet much safer. But it depends on how quickly researchers would develop methods for scaling AGI systems, either by building more supercomputers, or generalizing our code to run on more conventional machines. If this process takes years or decades we get to experiment with AGI in a relatively safe way. But if this step takes months, then I think the world ends in ~ 2000 or ~ 2010 (depending on our AGI arrival date).
Maybe?
