That's wise advice and we should all learn out tools.
We are both good photographers and both strive to "make the best pictures you can" (to quote you) and I agree. We would agree on lighting, composition and those other things that add up to make a good image.
However, where we diverge is what 'make the best picture you can" means.
You define making the best pictures you can as slowing down and striving the achieve the best technical file that the tech in your hands can deliver.
Whereas I define making the best pictures I can as nailing a decisive moment by setting my cameras up to be instantly ready for anything, at the expense of the very best IQ file technically.
This should be no surprise, as we photograph different things with different priorities.
It's not a question of not understanding anything, to me it's ALWAYS about relating that back real world scenarios.
