Another problem (which Tegmark writes about) is math will have to change. Some of the math we study will have to be part of illusion - there is no “one” math currently, and how could something exist in MUH which isn’t computable. His vision pairs down math, much to the ire of many mathematicians. But it is not unviable, we don’t need much of math for physics.
