This shows another longtime insight I think I have on math, I think tool-wise we are in the stone age of math. Every formula somebody writes down should automatically be an executable program that can be debugged or at the very least that has intellisense/autocomplete/documentation pop up over its symbols. Forget executability for now but even just having a convenient way of parsing a formula, havings its notation explained to you automatically.. that would be so important. Also I don't think that a math notation which has symbols that don't even exist on ascii keyboards should be acceptable. To me, math notation is a programming language like any other and it shouldn't be so hard to write it, find documentation for it, get autocompletion for it and to verify it. I get that math was invented in the time of paper and pencil but we need to find a way to write math more efficiently on the computer now so we can get better and faster at it, so people can copy and paste math on the internet without having to use picture formats or specialized software to render it. You probably agree that the vast majority of math papers are never read by more than two people, the original author and the reviewer. Imagine the alternative: Every paper could be like a programming library that should be plug&playable on the spot without even understanding it. Just hit that button on the top of the paper that reads "play" or "execute" and let's see the testcases/subproofs/partial proofs running green in a checklist. Then let's read the API docs to get which final formulas are usable to me now that you wrote this paper. Whoever sits at these prestigious journals in my opinion is already being paid for this very job: to make sure that papers are accessible. Well to me that also means development of tooling, conventions, etc. Not just a simple online search box where you might find a whole paper via a keyword.
"Is mathematics invented, or discovered?" is a never-ending debate."
I think that this is the wrong focus because I heard this question when I was younger and it made no sense to me. The act of asking that question (often playfully, probably somehow already admitting thereby that it's a wasteful question which is surprising in itself) was confusing to me because intuitively I think we all know the answer, it's obvious. But as soon as you ask, you imply that it's an open debate and thereby create confusion. Everybody already knows the answer: Math is obviously an invention in most ways because humans invented the symbols but it's also obviously an approximation of something inherent in the universe. We may not know the exact percentages of how close we are to the universe's true inner workings but that wasn't the question anyway.
