Why I didn’t sign the Fields medallists’ letter

    > we urgently need to come up with good ways of explaining the value of having a large pool of human mathematical experts, even if it is no longer part of their role to find new proofs of theorems.

    This is the main issue, and while I fully agree with that value sentiment, the Fields medallists’ letter failed to provide convincing arguments for why mathematicians should widely receive funding for merely understanding things, and how competition for postdoc and tenure positions would work under these circumstances.

      >why mathematicians should widely receive funding for merely understanding things

      imagine yourself living in the 1700s. how would you justify Newton and Leibniz's work on calculus?

      all maritime engineering and trade was done with geometry and arithmetic at the time. there were no practical applications, not for likely at least a century until hydrodynamics were incorporated into shipbuilding

      now look at today. how many of our modern technologies rely on the field having been birthed? that could only exist because of even further decades-worth of antecedent refinements, extrapolations, applications that had, at their time, no direct utilitarian cause?

      there's no KPI to be derived from any academic field of study at the bleeding edge of theory. theoretical underpinnings lead to practical applications much further down the line after many paradigm shifts

      semiotics and cultural capital as theoretical concepts is another example - at the time they were purely seen as navel-gazey literary theory work. these days, half a century later, they're in wide use (for better or worse) in marketing and advertising - they birthed the whole concept of 'branding'

      not everything needs immediate, quantifiable justification. to believe it does indicates a need for a period of self-reflection, to figure out how and when you became so heavily influenced by the MBA-brained propaganda that the world should revolve around the quarter-by-quarter creation of capital

        True, but this is also a stunning example of survivorship bias.

        Countless other mathematical curiosities were developed in the 1700s -- and forgotten. Calculus just happens to be the one that found practical applications later, so that's the one that's well known today.

        It's difficult to draw the conclusion that "every possible branch of learning ought to be funded" by appealing to "later practical value" based on this cherrypicked example.

        On the other hand, clearly _some_ novel theoretical work with no apparent immediate value _does_ yield real world benefit later.

        Since we lack the resources to fund every PhD with a crazy theory on what the next new subfield ought to be, how do we decide?

        Seems like AI could help massively there, by removing a huge bottleneck around technical elaboration and application seeking.

          No, it's an example of why you have to allow people to pursue what at the time look like "curiosities", even though most of them don't go anywhere--because the very small portion that do go somewhere, end up changing the world, and we don't know in advance which ones those are going to be.

          It's quite true that the funds we have for this are a finite resource. But that doesn't mean that "foreseeable practical applications" is a useful filter for how to deploy that resource.

            Yes you have to allow people to pursue these things. That's not a compelling argument for funding, especially when nobody was funding the people that did invent calculus.

              Of course someone was. Newton and Leibniz weren't living in autarky an some island. They had an income stream that was taken away from somewhere else and given to them so that they could afford working on their pet projects.

              The fact that it's not publicly funded doesn't change the fact that there's still resource allocation happening.

                I think by that definition every mathematician in the current day is funded, mission accomplished.

                  This is tautological, “mathematician” being defined in the modern world as someone paid to do mathematics…

                  Notice that the modern world is able able to sustain significantly more mathematicians than when “mathematicians” used to mean “someone well-off enough to work on mathematics in their ample amount of free time without worrying about their subsistence”.

                    Note that I'm including all the ones that a normal definition would not call paid, but your definition does.

                    But yes when a definition declares that everyone doing a thing is "funded", it does get pretty tautological and get in the way of arguments for actual funding.
