That is bad philosophy
Maybe, but he wasn't a professional philosopher, thank goodness.

saying the same thing over and over "quantum mechanics is weird"
Feynman was trying to figure it out.

BULLSHIT! Feynman predicted in 1948 that the magnetic moment of an
electron can't be exactly 1 in Dirac units as had been thought
because it is effected by an infinite (and I do mean infinite and
not just astronomical) number of virtual particles. He brilliantly
figured out a way to calculate this effect and do so in a finite
amount of time, he calculated it must be 1.00115965246, while the
best experimental value found much later is 1.00115965221. That's
like measuring the distance between Los Angeles and New York to the
thickness of a human hair, and Feynman got it right just by using
his mind. That's too good to be a coincidence, Feynman must have
been onto something good. Let's see a "good philosopher" like your
pal Feyerabend beat that!
Feynman was a giant in physics. No doubt. I just said that he was bad
in philosophy. I am not a pal of Feyerabend, nor of many philosophers
since 1500 years. Feyerabend is too much relativist to be taken
seriously when you study machine's (logical) theology.
