Wouldn't it be kinda cool if you could read a book and become an epistemic superman, showing up experts wrong in their own domains and being proven right?

When has this actually happened? I mean the part where just some guy with an above-average IQ reads the Sequences and starts out-predicting professional domain experts.

Also, regarding MWI: I don't regard it as even meaningful, preferring to declare that fundamental ontology is forever underdetermined by experimental data, and I should just shut up and calculate. There are researchers who try to do experiments that would distinguish one theory of quantum ontology from another -- I don't have a right to an opinion until I've seen their data.
