You bring up some interesting points and I'll readily admit that by being more interested in biology as a science and pretty much not interested in physics and math at all, I start at a deficit in this conversation. Biology is a lot easier for me to grasp, because a lot of the times the conversations are less about what a thing is in its absolute essence, and more about what a thing is in relation to everything else and all that can imply. For example, a dog is a dog, but it is also an animal, a mammal, a canine, similar to and distinct from other canines, a distinct ecosystem for internal bacteria, a component of the eco system around it, it's an animal that has shaped and has been shaped by the biological and cultural evolution of man, etc. and so on. The conversations that can be had around the single concept of "dog" are near endless because a dog is so many things while only being one thing at the same time. Where as in physics, if someone says "this is an electron," while there's a lot to an electron and what it does, I often feel like the conversations around them are frustratingly limited because people are willing to let themselves limit an electron to "just an electron."
That aside, I think in essence the issue I come across boils down to my disagreeing with this statement . . ,
There's no reason to fight against something that's so goddamned convenient and versatile, even if there are strong associations to them.
In one way, I don't think that trying to see beyond the limits of a concept is fighting against the said concept, nor rejecting it, nor having any antagonistic relationship with a concept at all. I see it as trying to see around, above, below, and through the concept to try to really get to know a thing as it really is, whether we're talking about an electron or a dog. Because both, while being quite different, are genuinely enormous concepts both as individual components as well as their relation to everything else that they interact with.
In another way, I think we're finally coming to a point, in mathematics, in language, in our ability to explore and discover things literally, and in our ability to explore and discover things conceptually, that we can really try to start understanding and describing things as they are, instead of relying on limiting and often misleading shorthand terms and descriptions. Simply put, we are starting to develop the capabilities to stop considering what things are like and instead really start considering what things are.
Please don't take this as me dismissing what you're saying or trying to antagonize you, because I understand and appreciate where you're coming from. I'm just saying, on a philosophical and personal experience level, "I disagree and here's why."
Edit: Added a sentence for clarification and emphasis.
