Same thing happening to Java. Lack of a strong enough pull to get people into it. If you are learning something new or just graduating, you're way more likely to learn rust/python/javascript as those languages offer something unique (low level speed/machine learning/browser stuff). Rails used to be miles ahead of the competition, but the competition has largely caught up. Rails is still probably the best choice(in my opinion at least) for building a feature-rich webapp backend quickly unless you've got some crazy unrealistic performance requirements(spoiler: most engineers love to pretend they do, but they probably don't) But these days there are frameworks everywhere so you can write your backend in whatever you're most comfortable with.
