I'd say it's a general trend in industry, similar to that in the 80's with their fourth generation languages. It happens when the current programming languages fail short of solving the most difficult problems the industry faces and programmers explore some paradigms that solve them nicely, but those paradigms haven't been integrated into a single coherent platform. This shift is pretty much happening with reactive functional programming - which solves asynchronous calls in the web -, and to some extent with large-scale module composition, which still lacks a good widely known solution.
