One of the biggest telltales about the decline of anything is articles related to it claiming it is not in decline despite general public perception. Sure, Ruby is amazing and sure Ruby on Rails is a great framework. But Ruby stalled right there -- RoR has been churning out regular updates and is still making strides in right direction, but look at Python and what happened with its community: the community didn't just stop at Django or Flask -- it went ahead in multiple domains and created useful libraries. The end result is, Python is used for far many types of projects (be it enterprise or robotics) where as Ruby is synonymous with only the Rails framework. This is why Python has eaten up any potential share that could have gone over to Ruby and if that is not all, the Academics in Universities around the World are starting to take Python seriously and are teaching it (NOT RUBY!!) and if there was any space left for those grumpy Java Developers at the Enterprise level, well emergence of Spring and Spring Boot has swayed them back into Java's fold.
