Moore's law is dead, that means developers who will not waste CPU cycles will be in demand for the next generation of compute intensive development. Big Data needs big compute so obviously these kinds of articles are not only pertinent but is the way ahead.

I would not be surprised if we do rewrites of all the past 20 year code in to Rust or Go or any other performant language.

Lets agree on this, you are smart and the author is right.

I am sorry people who are complaining are not seeing where the ball is going.
