Opening keynote by Matz: MythBuster
summary
Claims that static typing can be gained without annotations through RBS and TypeProf are backed by tools: TypeProf uses abstract interpretation to generate signatures, Steep checks them, and LSP integration gives real code completion. Performance work is concrete: YJIT gets a Rust rewrite with ARM64 and Apple Silicon support, MJIT remains as an experimental JIT, and Ruby 3.2 targets full Ruby in the browser via WebAssembly. Survey numbers show 13 of 50 startups use Ruby but those represent 52% of total valuation, arguing for continued investment in velocity and tooling.
