We're basically getting a huge Algol mono-language.

C is not really moving, but C++ is also converging towards this Java++ language.

Java itself is finally moving.

C# is a bit ahead of the curve, because it can follow the trail blazed by F#.

PHP started moving towards Java back from when PHP5 was introduced.

Javascript is moving towards Typescript which is following C#'s lead.

Python is kind of the only non-Algol mainstream hold out.

Did I miss any of the big enterprise languages? :-?
