You're only rich if everyone else is poorer than you. At the point Golang, Javascript, Ruby, and Python (these are just the ones I use) have huge completely open source ecosystems. Java's ecosystem is no longer a convincing argument that we should ignore everything else about the language and it's place in the current line up.

No, they are all rich. But I would really hesitate to compare java to js, python, ruby, etc. They aren't as interchangeable.

I use all those languages too. Use the right tool for the job. Don't be dogmatic. And don't disparage others.

Would I start a new project in Java? Probably not. But I might reach for other jvm languages that were mentioned elsewhere. I'm definitely not too cool to work on an existing Java project. It's fine.

Don't conclude that someone is being dogmatic without compelling arguments. Java is a technology, it's ok for it to be superseded by changes in the landscape. I also never said that people should stop using Java, I simply said I felt bad for the people that had to work with it given that it's obsoleted by improvements in sandboxing, package management, and language design.
