Keynote
summary
Language starts in 1993 and grows from one user to over a million, pick-axe book sells ~10,000 copies and first RubyConf has ~30 attendees while EuRuKo hosts a few hundred. Work targets compatibility plus performance: generational and idle GC, heap compaction, and a JIT prototype shipping with Ruby 2.6 in December that shows JIT prototype (up to 6× on benchmarks) but may slow real apps. Concurrency moves toward actor-like solutions, typing favors tooling and inference like runtime type aggregation and projects such as Sorbet and Steep for typing.
