Let's talk about the current state of the Nix language and evaluator, and where things are headed. Nix lang2 (https://wiki.lix.systems/books/development/page/nix-lang-v2), language versioning (https://github.com/NixOS/rfcs/pull/137), bytecode, Rust and more.
This will be more like a semi-structured infodump with some Q&A than a proper talk. Slides are unlikely to be prepared for this. No public recordings, but the plan is to take the transcript and compile it down into a blog post or something.
