The majority of the web isn't powered by Ruby now. We have a hodgepodge of PHP, C#, Java, Perl, static, Node, Rails and other Ruby frameworks, Python, any I missed?
People have been proclaiming the death of Java for how long now? And it's still going strong. I'd argue that Ruby will last even longer than Java because it's a nicer language and has more room to grow. Ruby you can port to other runtimes, Java, why bother? It won't outlive the JVM.
The only thing I think that could replace Ruby is Lisp. Maybe in 10 more years Racket will where Ruby is today. I doubt it. By that time, Ruby will be where Java is.
