So! Will I still be a Rubyistin 5 years?

51.
YES! But..– Most unpredictable arena is the future of webdevelopment– The future is polyglot, but once you start thinkinglike a Rubyist it is hard to stop – even if we’re notalways typing it– The irresistible urge to inject Ruby goodnesswhere-ever we tread
