Nothing to do with 2020.
Some people can't face harsh reality and need beliefs to comfort them.
That's getting off-track.
Does Emmy fear death?
Ministers once preached against anesthesia in childbirth because Genesis said "women should suffer pain." Queen Victoria told them to shut up!!
If there was a pill which could give you another century of healthy youth, would you refuse it because it's "un-natural" and you're in a hurry to Meet Your Maker?
I'm sure nandroids have an instinct for self-preservation. You wouldn't want an expensive maid carelessly crossing against the light. But it's not their first priority. Emmy would sacrifice herself to save Madeline (and maybe other humans.) But they don't fear death so long as their owners are willing to pay for their maintenance.
Obviously, Emmy and her kind are still fantasies. We can't even build cars smart enough to consider deliberately crashing, wrecking themselves and their owners, to avoid hitting a group of a dozen jaywalkers.
