Story of Matrix movies goes something like this:
Humans develop AI. In year 2100 or so, AI starts killing humans. In an attempt to stop AI, humans block out the Sun, because AI cant survive without sunlight? Well, the story probably isnt perfectly written. But anyway, AI finds a new source of energy by using humans to generate energy, but to keep these humans alive, AI not just feeds them yucky food, but also for some reason created a fake virtual world where these people believe they live in 2009 or whatever, and virtual world to them looks 100% authentic and they dont even know its a virtual world.
It is theoretically possible that current year is 2200 or 2300, and you decided to try out living a life in 21st century again so you turned on this simulation and entered it like playing games which in future will anyway likely be 100% like reality.
However, this theory can only be true for people like Trump. No ordinary person would choose to live the life they live in this simulation. So ordinary person is likely just a computer program.
