I may be stupid and I am indeed but it is insanely straightforward today (not tomorrow) to put a gun on a drone and tell it to image recognize some targeted 1.3-2.3m tall biped with oval head and shoot him/her down.
Is your point that there are unaddressed safety concerns with existing tech? While true, none of them are really existential threats, whereas something with greater than human intelligence yet none of the limitations of a single biological body to upkeep is such a threat.
