I was reading Dirac's Directions in Physics and he talks about how he is not satisfied with the renormalization process. He believed it was a major flaw in quantum field theory. Is this still a tenable view? Is renomalization understood differently today or are we just more acclimated to it so we don't question it anymore out of habit?

It is understood differently due to Wilson and Polchinski. – Connor Behan Sep 08 '22 at 16:37
