Ceylon isn’t Java, it’s a new language that’s deeply influenced by Java, designed by people who are unapologetic fans of Java. Java’s not dying anytime soon, so nothing’s killing it.

Most comparisions take 5 to 10-year-old brownfield, legacy Java projects with hundreds of developers – many of them average – and compare them with 2-year-old Rails projects, where the initial developers – most of them excellent – are still on board. For a real comparison one would need to compare state of the art frameworks, Webbeans/Wicket, Stripes/JPA with rapid development frameworks like Rails and Django. I’ll spare this comparison perhaps for another post in the future, but would be happy if someone does a decent comparison. I consider this question open.
