Your avatar is your personality, appearance. We are close to simulating all our experiences.
The only thing real will be a climate-controlled-with-plumbing 20 x 20 room and the food we eat. (We still haven't digitized taste, smell and some forms of touch).
Given this scenario, Reality is over-rated. Why do you need "truth" anyway?
Who cares if someone believes the earth is flat? or Trump is still the President or some esoteric grammar rules? As long as there is one another person (or even an AI assistant) who believes the story that's all that matters for our social well-being
