    The Lean Kernel Arena is a public benchmarking site for Lean proof checkers. Anyone can build an independent Lean kernel. The Arena runs them all against the same suite: valid proofs each should accept, invalid proofs each should reject, plus timing and memory on Mathlib and the

    I updated my 2023 roadmap diagram to overlay where the items that were there sit in the current Strawmap ( strawmap.org ). In general, a lot of overlap, but: * Some things got reshuffled in order (eg. quantum safety up-prioritized) * Some things deprioritized (eg.
