It seems, given the end of Moore's "Law", as well as environmental concerns, that language efficiency will get more attention. It'll be interesting to see if languages like Swift, Rust, and Julia can gain traction for web development.
I wonder how uptake has been for IBM Kitura so far...
Yet Go is blazingly fast compared to most other languages that are widely used for web server development (except, maybe, Java).
