The next king of the hill

F#, R, D, Go.

Which will dominate the industry in the future?

If you know C and keep up with the news you should already have a good guess.

While most of those languages are improvements over existing ones (D > C++, Go > C), they're not _enough_ of an improvement to make companies switch and face the massive upheaval of rewriting code bases, finding new libraries, retraining staff etc.

The industry is typically slow to move onto any new language, unless:
a) A major software company pushes it, like C#
b) A key piece of software is written in it, the way shitty PHP has some very notable software

As for F# - functional programming is never going to be more than an academic niche, because of the bottom feeders which make up 90% of corporate programmers.
