The best interpretation of quantum theory [..] takes the [..] view that randomness is genuinely physically manifested We could argue endlessly about whether that is 'the best' interpretation (which ethical assumptions does your 'the best' presuppose?) but fortunately it doesn't matter. As Mermin (from the famous Ashcroft and Mermin book on Solid State Physics) famously quipped: you can 'shut up and calculate'. The usefulness of the model does not depend on its interpretations (although the interpretations are certainly important with respect to scientific progress).
