I agree. If your argument is that doing X in language Y is bad because you have to write a few extra lines of code, and therefore no one (meaning the author) does X, that's an argument that reflects most poorly on the author himself.
You haven't made your Java webapps robust and tolerant of failure because you don't like the extra 3 lines of code you have to write? That makes me question you as a developer and the value you place on things, not the language/ecosystem.

Quite the contrary. I (the author) have done a lot of asynchronous Java development using promises and other asynchronous constructs. The boilerplate is a cost that I'm willing to accept.
However, in my experience, working with other Java developers as well as consulting and providing support to quite a number of enterprise companies full of Java developers, I find time and time again that it is not a cost that other Java developers are willing to accept. You provide them with fluent async libraries, you educate them again and again why they shouldn't block on calls to remote clients, you provide sample code, and they ignore your advice because the code is too hard to read. I'm not saying that all Java developers are like this, I'm just saying that from my observations working across many enterprise companies, most are like this.

And do you think those developers are likely to adopt Scala?
That's like publishing an article proclaiming C++ is slower than JavaScript because it's hard to program correctly.
Java is one of the most popular languages and so statistically you're going to find a lot more poor talent out there. If they can't handle 2 lines of boilerplate I shudder at the horrors those same folks would unleash with Scala.
