In this essay I argue the following:
Brain emulation requires enormous computing power; enormous computing power requires further progression of Moore’s law; further Moore’s law relies on large-scale production of cheap processors in ever more-advanced chip fabs; cutting-edge chip fabs are both expensive and vulnerable to state actors (but not non-state actors such as terrorists). Therefore: the advent of brain emulation can be delayed by global regulation of chip fabs.

TBH i'd rather share my planet with the mind uploaded folks than the folks that bomb factories. Both of those folks are potentially non-friendly non-me intelligences, except the latter type is for certain non-friendly while the former type might end up friendly enough in the sense in which corporations and governments - as meta-organisms - are friendly enough.
