No, definitely not only in that sense. GC is a boon to productivity no matter how you slice it, for projects of all sizes.

I think the idea that this is not the case, perhaps stems from the fact that Rust specifically has a better type system than Java specifically, so that becomes the default comparison. But not every GC language is Java. They don't all have lax type systems where you have to tiptoe around nulls. Many are quite strict and are definitely not "move fast and break things" type if languages.

Well if you think Java doesn't have a sufficiently good type system, then surely Go is even further from one?

Not saying those are the only two GC languages, just circling back to the post spawning these comments.
