Philip K. Dick's "The Second Variety" is far more representative of our likelihood of survival against a consistent terminator-level antagonist / AGI. Still worth reading, as is reading the other book "Soldier" by Harlan Ellison that Terminator is based on. The Terminator also wouldn't likely use a firearm to try to kill Sarah Connor, as xkcd notes :) ...but it also wouldn't use a drone.

It would do what Richard Kuklinski did: make friends with her, get close enough to spray her with cyanide solution (odorless, undetectable, she seemingly dies of natural causes), or do something like what the T-1000 did in T2: play a cop, then strike with total certainty. Or, a ricin spike or other "bio-defense-mimicking" method.

"Nature, you scary!"
