Demand for Ruby developers is over 5 times greater than for Python developers and nearly 10 times greater than for PHP developers, as over 600,000 websites now run on the Ruby on Rails framework. Knowing alternative frameworks beyond just Rails, Unix commands, and how to work directly with databases will help Ruby developers write faster, more secure code and build applications with better user interfaces that consume fewer server resources. Ruby is predicted to have a great future due to its active and responsive community, popularity among startups for its agility, and increasing maturity with each new version.
