I read indeed.com job openings regularly to see what's still in demand and I feel like I've seen a big drop over the years of jobs looking for rails developers but I'm sure github and these job sites have more official stats. Java and JavaScript languages have been jumping in native development a lot more and I think that's a large part of it.
