Why do we need human mathematicians anymore?

    I consider myself an applied mathematician though technically I’m an economist (macro models, mostly) and operations researcher and differential game theorist (odd combination, but whatever). For context I’m 45 and I’ve spent most of my working life in corporate life.

    I’ve always been at a disadvantage academically because I’m rather clumsy with my manipulations, derivations, and I’m a disaster at mental arithmetic. I’m also dyslexic. But starting in the late 1990s when I was in High School I started to become fluent with CAS (Computer Algebra Systems): first Derive, then the Symbolics capabilities of Mathlab, and ultimately Mathematica.

    The whole transition is turning out quite well for me: I’m now able to delegate exploring my intuitions to increasingly powerful tools, I no longer have to haul the pyramid blocks up the ramp myself but I can drop them in by helicopter (as if were) and what I bring to the party is intuition and understanding.

    I view it a bit like astronomy: in ancient times, before telescopes, keen eyesight was a prerequisite to be an astronomer. Later, after telescopes, anybody with eyesight had enormously enhanced capabilities of observation, and now, with radioastronomy and other forms of remote sensing (neutrino observatories, gravitational interferometers) the whole field has opened up to people who by virtue of being blind would’ve literally been excluded only a few decades ago.

    Go forth and multiply: everybody can become a mathematician now. There’s an infinite number of potential universes out there with an infinite number of facts to prove and disprove. And while we’re at it: there’s so much more to mathematics than conjectures, proofs and counterexamples. Solve, model, approximate, fiddle around: as long as you’re not doing trite numerics on arbitrary systems of equations you’ve cooked up for your own amusement you’re good in my books.

    Enjoy the tools. Keep your wits about you. Work through the steps that are presented to you. Build your intuition. HAVE FUN.

      Hauling the pyramid blocks is what gives people intuition and understanding. It is true that school systems usually have way too much computation -- it is easier to test and grade computation. But the only way that you were able to use computer algebra systems fluently is because you had internalized how algebra worked by hand. If we tell students that they no longer need to learn how to solve equations we are seriously depriving them of a mathematical education.

        This might be clumsy but I will say it anyway. If music is math, how do you explain people who have innate musical abilities without formal academic training in notation, music theory, circle of fifths, etc.

          Math isn’t music, even in a metaphorical sense. The argument by analogy fails at the first hurdle.

            Just to make sure I follow, do you mean the "music is math" idea fails, or that my question does? I'm not saying math has nothing to do with music. Frequency ratios and rhythmic divisions are clearly there. My point is that you can have deep musical ability without ever thinking in those terms, which suggests music is more than the math that describes it.

              Sheet music is no more music than mathematical notation is mathematics. (Indeed both notations have roots in the same kind of two-dimensional seventeenth century calligraphic tradition.) However, as you point out, mathematics is indeed the study of patterns, structures, and relationships, and music is not. It is a structure and has relationships, but it is not a “metaphor of metaphors” as mathematics is. Case in point: modern visual art post-photography is much more affine to music than mathematics is, because after depiction became not quite trivial but literally photographic from the daguerreotype onwards, the role of the visual arts became the solicitation of emotion and the conveyance of narrative. Music has syntax, indeed it has very many, but it is not the study of syntaxes in the manner in which mathematics is.
