rv, a ruby manager for the future

There’s a new kind of developer tool, combining version manager, dependency manager, environment manager, and script runner. The biggest “language manager” is `uv` for Python, but we can and should have one for Ruby. In this talk, see how we are building `rv`, including why we're using Rust, the new use-cases it unlocks, and how it can be faster and easier to use Ruby than it has ever been before.
