Well, at least the serious ones. In recent years, software got much slower, basically killing all advances in hardware performance. Finally, software performance got to the front of debate. Yet the discussion is often twisted toward things that do not really matter. One such myth is that there are fast and slow programming languages, while in fact the difference in speed is rather negligible. Furthermore, languages differ in power, so it might make sense to trade a bit of performance for it. I will showcase this on my favorite programming language Clojure.
