Ruby Committers and the World
summary
Covers concrete proposals and measurable outcomes: a push for String popcount and byte/bit APIs with MSB/LSB indexing debate; governance options including a small council or an AI-based Mecha Matz idea; committers report heavy AI use (several say ~80% with Claude Code, roughly a third use AI >50%); an AI-driven, ~7,000-line date library rewrite from C back to Ruby with tradeoffs in readability and performance under JIT; setjmp/longjmp blocking JIT optimizations; deep_freeze and frozen string/array plans.
