2112

Assuming the aliens haven't already taken over by then, suddenly finding yourself in the year 2112 would be a jarring experience similar to being born back into babyhood (with the exception that you can speak really antiquated English and have a vague background in decades old etiquette). In all likely hood, you would be taken up for study and probed with various unrecognizable instruments to determine your health. You'd probably get some sort of media attention (assuming the media is still a thing at this point) and be promptly hooked up to whatever bio-medical junk they can throw at you and inoculated for modern diseases. After a quick rundown of modern society, you'd probably be thrown into the masses or sent off to moon-base or something like that. It would literally take years to figure out how life worked and how to use new technology, but being a tech-savvy teenager has taught you how to adapt to new interfaces. eventually, you hook up to the brain-computer interface to connect your brain to the internet. What an experience that is. full access to all of human knowledge, ripe for contribution and consumption. One day, while surfing the neuralweb, you come across a bit of old music and remember all the good times you had in the 20th and 21st century.
