Holographic universe is not a concept proposed by pot smokers and those who drop acid. The notion that we literally live in the Matrix has been proposed by scientists, truthers, mandela effect freaks, and even Elon Musk of SpaceX. When the world is this strange it may be time to question reality itself. Quantum physics has told us for 60 years that particles both exists and not exist (as photons) depending on circumstance or observer. Do we live in a simulation? In my opinion, at this moment this is the best explanation we have. We live in some sort of matrix.
