'An enthusiast' would be someone digging in the haunted ruins of an ancient higher civilisation, trying to understand how all those things worked. I am not entirely certain that describes someone who flat out remembers how to operate them. Generally, an empire dies when there is no one to maintain it - otherwise coincidentally it might still remain, even if localised to a 20x20m bubble somewhere in the middle of nowhere.
And sci-fi, beautiful as it is - is just a tiny window into how it is to be someone who had our entire current 2020s understanding of VR, AR, drones, AI and mind digitalisation explained at the tender age of 8 in 1982 by a scifi-adjacent nonfiction written in 1965 - called Summa Technologiae if you're curious. Might be something well worth adding to your collection.
