Very true! I think a lot of the accidental complexity of early Java systems were rooted in the not so powerful language. If the language is too powerful (like Scala 2) developers do insane things with it. If the language is not powerful enough, developers create their own helpers and tricks everywhere and have to write a lot of additional code to do so.

Just compare Java streams with how collections are handled in Go and scratch your head how someone can come up with such a restricted language in this century.
