> Once again: when?

When it's ready. Again, because of Java's position, we aim for features that will work well for decades rather than those that will grab some more users now. I know this is hard for some to understand, but the main complaint we're getting is that Java is getting too many features too quickly, not the other way around. The people who like lots of features are a minority; a large one, but still a minority. Whether we add a feature or don't add it, some people will be disappointed. It's impossible to please everyone, so we try to please the majority.

> Ahahaha.

    var list = List.of(
        "carrot",
        "fox",
        "explorer");

    var array = new String[]{"carrot", "fox", "explorer"};

This is not where we think the language's complexity budget is best spent. When we do add a feature to the language, we want it to have much more bang than that. Those who like lots of features don't like that but, again, they're the minority. I cannot stress enough how much people hate language features. Language features don't have Javadoc, and people have to learn them. If they have to go and learn a new feature, they expect it to be worth it.

> I'm really surprised records made it into the language with this approach to things.

You mean the approach that has consistently made Java so successful? We try to add as few features to the language as we can afford to, which means that we make the features we do add extra powerful. This gives us room to add some of the features people will be asking for in ten years, rather than waste all of the complexity budget now.

> "why didn't Java adopt these?"

Because Java's strategy is different, and it's working better.

> But every time I need to write or implement and write another X.builder().setX.setY.setZ.build() instead of `new X { x=.., y=.., z=.. }` I want to claw my eyes out.

With that I completely agree, which is why we'll address that.

So, I'm likely to be dead by then.

Why are you adding all these features from all these "non-successful languages" then?

Why is it that dealing with long chains of setter methods isn't "spending complexity budget" and is a "feature more bang than that" (whatever "that" is), but adding literally the same thing: better ways of working with collections is "no, we don't adopt features from less successful languages".

The issue isn't the features themselves but the evolution strategy. Sure, we've been adopting most of the features added to Java since 1995 from ML (1972-3) and we're nearly done, but what we don't adopt is the approach of adding lots of features that each help a little. We like few features that help a lot.

We don't adopt an evolution strategy -- not features -- from less successful languages just because they're doing it. Java's strategy has been to innovate quickly on the VM (and we're innovating there more than anyone else, I think), and keep the language relatively conservative and relatively slow-moving. And it seems that more people like it this way. For the others, we make sure that the platform supports a choice of more feature-rich languages with good interop.

But the answer to your question is that we're trying to add as few features as we can (to leave room for growth in the futures, as requirements and fashions change again) and we believe that the features we do add help more than the ones we don't. Still, at the end of the day, there's hardly ever consensus among developers on anything. Whatever we do or don't do, some people won't like it. What's important to remember is that even if in some cases you don't agree with the language team's decisions, they are among the most experienced and successful language design teams in the history of software (I can say that because I'm not on the language team). They might make mistakes from time to time, but overall, they know what they're doing. In any event, the argument that millions of people prefer Pepsi to Coke is not the one that will convince Coke to change its flavour to that of Pepsi, because even more people prefer Coke.
