Here's the argument I have been making over the years:

1) The important purpose of mathematics is to provide a conceptual framework for reasoning about the real world. IOW, mathematics is the language of science.

2) We should apply Occam's razor when building a foundation for mathematics: we should minimize the number of assumptions we make, or as Einstein reportedly put it, everything (e.g. the foundations of mathematics) should be as simple as possible, but no simpler.

3) Every abstract principle that is essential for reasoning about the real world (i.e. essential to science) should be formalized and integrated into the foundations of mathematics. Mathematicians should accept it as their moral responsibility to produce something that is beneficial to society.

4) Over the last century or so, there have been several advances in our understanding of scientific reasoning for which there have not been any corresponding advances in mathematical reasoning, and this is something that needs to be corrected.

5) The advances in scientific reasoning that I mention most often include reasoning under uncertainty and falsifiability, though there are others. These can and should be formalized and integrated into mathematics at the foundational level.

6)The reason that mathematicians reject the ideas that I put forth is because if they accepted them, they would be forced to admit that Cantor's set theory is not essential for scientific reasoning, and does not belong in mathematics. Cantor's set theory cannot be included in a consistent way with the modern advances in scientific reasoning that I suggest should be accepted as part of mathematical reasoning.

7) Since there are many outspoken mathematicians who label anyone who suggests that Cantor's set theory doesn't belong in mathematics as a stupid, delusional crank (or worse), and the mathematics community as a whole does nothing to reign in these outspoken mathematicians, the (pure) mathematics community as a whole should be seen as fraudulent.

_An_ important purpose, but not the primary one.

This is currently done. The foundations of maths are currently based on
set theory, which only contains a small number of axioms.

Why should they, any more than any other academics, or indeed anybody
else at all?

There have been great advances in mathematics.

Absolutely not. Mathematics operates under different rules from science.
Falsifiability doesn't apply to maths.

Why get so personal? Set theory is currently essential for the
foundations of mathematics, and as such, is needed by science. If you
disagree, perhaps you should consider the question "what is a number?".

> .... and does not belong in mathematics.

On what, then, are the foundation of mathematics to be based? If you
want that to be something other than set theory, you must research and
develop some alternative.

They're probably right, though none that I've known would express
themselves in such a manner. Can you give an example of such an
"outspoken mathematician"? I suspect they are few in number, if indeed
they exist at all.

Such an attitude would be much milder, if these critics of set theory
(why does it always have to be personalised as _Cantor_'s set theory?)
proposed something else to put in its place.

Your tone of expression has now descended into crankery.

that depends on the accuracy required, over the dimentions included. Simple models are less accurate. Many problems do not have accurate solutions
either, so your #2 applies to the simpler problems.

Why put abstract foundations into math ?

A feel good thing, not a requirement.

can you be specific? or are you making stuff up again ?

can you be more specific ? What areas of Math are you talking about ?

Wrong. Cantor and his sets have nothing to do with it, you are not specific, your at 200,000 foot level.

Not true at all.

you mean WM.

UKRAINE BIOLABS – 5 . U.S. Department of Defense granted a ‘COVID-19 Research’ 3 months before Infection Disease was known to even exist
https://www.gospanews.net/en/2022/04/14/ukraine-biolabs-5-u-s-department-of-defense-granted-a-covid-19-research-3-months-before-infection-disease-was-known-to-even-exist/

Why did the Department of Defense pay a company that is allegedly “a global engineering, procurement, consulting and construction company specialising in infrastructure development”, to help implement a “Biological threat reduction program in Ukraine’?And why did both the DOD and said company then pay Labyrinth Global Health INC to carry out COVID-19 research in Ukraine at least one month before the alleged emergence of the novel coronavirus, and three months before it was officially dubbed Covid-19?
