It's hard to believe that a world where Ruby, Python and Node are massively popular cares about performance above expressiveness. Even Java became popular first and fast afterwards—not even talking about memory efficiency! I'd agree that a lot of developers still over-index on performance though, probably because it's sexy and easy to measure.

To keep producing responsive compute programs as the complexity of those programs continues to rise while the single-core CPU performance remains steady, program performance must become more and more important.
