While one can grasp the basic idea of MWI without knowing the actual math of the quantum theory, such knowledge is pretty pointless, since it basically involves taking a controversial view on pure faith.
Are you going to claim that you believe into AI going FOOM based on the actual math? Why would you care about how founded MWI is if you accept the basic premise of risk from AI to an extent that you donate to some institute with Singularity in its name when not even gravitational singularities are proven beyond the point that people would ground a movement around them...
