There's actually more stuff like this than the author might think. "Prey" (2017) is a game set in a space station orbiting the moon, only for it to be revealed at the end that it's a simulation/test to gauge the humanity of the main character/player, and with the implication this is far from the first test. SOMA is a horror game that gradually reveals you are simulated person in a underwater exploration suit, and provides well-constructed and disturbing examples of what this implies - there's zero indication of time between the point where your brain in scanned initially (some point in the late 21st century) and when the simulation is booted up from that scan (a hundred years later). At one point, your character is conversing with another person running inside a small portable device; you disconnect her mid-sentence, do other stuff for half an hour, reconnect her, only to hear her continuing that sentence exactly as if no time had passed (as for her, none did). SOMA also has you move from one body to another, and shifts your perspective - but you can hear your initial self in the first body is still active, and will be trapped there forever, while you move on in the new one. There's others - Eclipse Phase is a pen-and-paper RPG setting/ruleset with an emphasis on transhumanism and horror; Ghost in the Shell touches on some of these themes occasionally; Moon considers some of these ideas from a physical cloning aspect; and of course there's a range of SF writers. How much and how deeply this makes it into the popular consciousness is another question, of course, but I think it'll increase in the coming decades.
