Yeah, i have asked myself this, and have repeatedly tried it. Somehow it usually doesn't work out as well. With gems it's still a bit too easy to dig into a gem and fiddle with it to get something done quickly when in a hurry breaking the encapsulation. Maybe there are other reasons as well. Also, with a big org I like having the ability to use different languages and technologies in some small services. Is functional programming all the rage? Well we can experiment with it on this little service need to build without much risk. Another thing I like is that other teams can leverage my micro service regardless of the languages we are using. With libraries, everyone has to use the same language.
