    I've moved from Rust to Go for most things because in the era of agents, being able to iterate quickly on a project is a huge advantage and Rust is way, way slower than Go for compilation. There are times when Rust is more appropriate, but for the vast majority of things Go is perfectly fine.

      I nearly did this, but then I swapped to writing native desktop apps and egui - Rust is still worth it.

      I've stopped using Tauri and gone with 100% egui. It's cross platform and excellent, and if you give it design constraints it will look beautiful.

      Check out my 100% adobe clean room reimplementations:

      The #1 thing for the Rust project to do is make Rust faster to compile.

      Rust is the agentic AI language. It just needs to lean in and go faster.

        Are agents able to control these well? I saw vector craft mention MCP and a command api. Whats the command api? No CLI it sounds like.

          Working on it! That&#x27;s the intent for all of these.

          Going to do Toon Boom and a few others too and build them as a suite.
