Unfortunately, you (and I) also never change our minds because of adversarial debate. It's easy to tell other people "you should change your mind", but it's hard to think "I should change my mind".
In my opinion :) it should be a badge of pride to be willing (and demonstrably able) to change ones mind about important matters.
In science it's also their grant funding and reputation, that is at stake.
Well, at least in computer science (ML) it's not what I see. It's very much empirically driven and with a heavy engineering vibe. A little bit more science would often help imho, but papers without strong result are hard to publish, even if they improve our understanding of something. It sometimes feels a bit like a large corporate research lab, which is only a small part of science. We do not only create, we want to understand!
