Did Feynman believe in the many-worlds interpretation of quantum mechanics?

No, Feynman ? who was a student of John Wheeler, much like Hugh Everett ? didn’t believe that it made sense to think that the wave function was “universal” and/or that there were many worlds.
In fact, Feynman was arguably the first person in the world who pointed out that Everett’s strange ideas meant that there were “many worlds”. According to Feynman, this was a source of “serious conceptual difficulties” of the whole Everett program. Everett’s ideas were wrong because they led to the many worlds!
