It seems that a few years ago several big name tech companies found themselves at the limit of what they could do with the c#/java style languages. But they weren't willing to go back to c/c++. Facebook started experimenting with D, apple created swift, google created go, Mozilla created rust, Microsoft had a rumored system language that never seemed to materialise, and even c++ is trying to get away from itself.

It is sort of looking like the industry as a whole is starting to see if there isn't a better way to do things and I think we will see how things shake out in the next five years or so.
