> still they are seldom used in serious software This is mostly because the majority of software developers only know Java and are averse to learning new languages. Also, companies chose Java at one point and are now taking next to no risks by introducing new languages (not even languages on the JVM). They can also just fire and rehire Java developers because there is a large pool of available developers that they can just plug-n-play, so to speak. They're not interested training people.
