      A formally verified Lean proof of the sensitivity conjecture, on Github: https://github.com/leanprover-community/mathlib/blob/3f216bc6a2c3729391ca1c8aaaf156fc96e7f10e/archive/sensitivity.lean#L389-L390 … More readable than I guessed (admittedly, a low bar), and very striking to see a significant result given a short formal proof.https://twitter.com/XenaProject/status/1260276915652485120 …

      Are you sure that God doesn't think about the proof like this: https://github.com/leanprover-community/mathlib/blob/3f216bc6a2c3729391ca1c8aaaf156fc96e7f10e/archive/sensitivity.lean#L389-L390 … ? That's a formally verified Lean proof of the conjecture.

      As an outsider, it's been exciting to watch the progress of these kinds of systems. I was very skeptical of them for a long time. But I was probably mostly wrong, or didn't appreciate their value.

      Can't resist adding an orthogonal direction that I think has been underexplored: formal systems to support the heuristic thinking people use in creative problem solving.

      Solar-Lezama et al. advocated for sketch-based program synthesis as a means of algorithm discovery, e.g. to invent Karatsuba's multiplication method. ("Combinatorial Sketching for Finite Programs", ASPLOS'06)pic.twitter.com/bbr7ntA9iC
