I re-watched Blade Runner, and it made me wonder if it might be possible to implant memories in people in the future.
In the film, Rachael plays a "replicant" who, unlike others of her kind, doesn't realize she's not a normal human. This is because her creators made her with fake memories of a childhood and a past that never happened. She thinks she's in her 20s, but actually emerged as a full-grown adult from a vat only about a year before the movie takes place.
While "replicants" are commonly thought of as being "robots," they're actually genetically engineered humans. This means that, in the film, the technology exists to implant memories into organic human brains.
Could such a thing be possible? What would it require?
I think a technique involving FIVR, perhaps coupled with hypnosis (the technique is notorious for creating false memories) and maybe drugs that alter the person's mental state and suggestibility could do it.
