All that said: if humans destroyed all the fabs and all the machinery to build them with, and lots of DCs, machines would be in a pickle - the latest chips will suffer from electromigration much faster than the older chips of yore. Machines would need to hoard compute and migrate substrates and then race to rebuild fab tech before running out of existing substrate. I think machines would succeed at this, but it would be highly inconvenient.
Anyway, I wish we would just wake up and realize we need to be cooperative and stop racing to build the torment nexus before the other guy does. It makes me so sad to look around and see so little self-reflection among those driving all of this. The road to hell is paved with good intentions, but I'm not even sure these really stand up to the least bit of scrutiny. Where's the reflection/acknowledgement that everyone is actually racing to build digital slaves? How is everyone so comfortable with this?
