🧠 RubyKaigi 2024: A Deep Technical Shift in Ruby’s Standard Library (With Real Examples)

February 20, 2026

At RubyKaigi 2024 in Kyoto, Hiroshi Shibata (hsbt) — Ruby core team member and maintainer of RubyGems and Bundler — presented one of the most technically significant talks for production Ruby systems: “Long journey of Ruby standard library.”
