Nice point about a time limit safety device. With their technical know-how, it's not difficult to implant a reliable small device that activates just before the deadline and does the same thing the Giftia erase gun does. Then they can use the more elaborate and funeral like procedure they have, and still have a proper fail safe for difficult cases. But you lack some fear, needed for drama I guess.

it sure feels a little dumb there's no fail safe, after we learn giftia's have been around for at least 20 years, since the old lady had had a different personality in the same Giftia multiple times already.

I know that show is flawed on multiple levels, but it makes for an easy late evening watch after a hard working day.
