      The dogma that mathematical proofs could, in principle, be turned into logical proofs remains a conjecture; it is not feasible in practice. Existing proof systems are not up to the job; can they be beefed up sufficiently? Research community disconnect!https://xenaproject.wordpress.com/2020/02/09/where-is-the-fashionable-mathematics/ …

      Mathematicians aren’t interested in computer proof systems because they aren’t (yet) useful in practice. Proof system people don’t care about “real” math because… it’s too hard? (h/t @JohnDCook for OP)

      Resonates with @michael_nielsen & @andy_matuschak’s point that “tools for thinking” have to be driven by the needs of expert professional users, not someone’s appealing theory of education or cognition or philosophy of math or something

          (I should say that computer proof systems are occasionally useful for computer system verification. It’s “real math” that they aren’t (yet) useable for.)

          Ask me about the history of "mind mapping" / "concept mapping" / "network mapping" tools. Basically all of these have failed because... a) most people don't need to think that way for most tasks b) when they do, a whiteboard works extremely well

          Yes I’ve always been baffled by those for just that reason. Some people claim to find them helpful though

          This is just "skin in the game" no?

          The question, again and again, is not "how can we reason this from first principles" but "what filters bring the most correct/useful result to the top."
