For now perhaps, but now that reality has been proven to be a holographic as of 2022 theres going to be tons of people trying to figure out if localized realities are created by the observer, what is it that makes the rest of reality for lack of a better term construct itself into these so called classical mechanics, and it won't be long before some of them start figuring out that the mandela effect isn't some weird mass hallucination.Well that's the problem. We know that quantum stuff behaves in a quantum way, but the observable world behaves according to classic mechanics. Theories like MWI try to explain why that's the case, but there are other theories, too. MWI is an unfalsifiable hypothesis. That doesn't make it wrong of course, just that it can't be proven wrong.
Once they figure out that its real, that groups of people have created groups of timelines then they will start looking for the parameters involved and eventually figure out that resonance of belief systems create it, and that that resonance is measurable.
