> Java has made a U-turn in adding streams and related functional features on top of a language that used to be strongly for OOP (actually defining the meaning of OOP for a generation of developers.)

So, by adding a feature which works extremely well with OO and enhances the language they have no soul? That doesn't make any sense. Javas soul is being a blue collar language. It leaves the experiments to other (JVM) languages and takes the parts which have been shown in the field to be useful for many cases.

Go on the other hand is a half-finished Java, produced for the sake of saying "We are Google, OF COURSE we have our own language".
