I was weary when I saw the headline but clicked it to see if I could learn something new.
The article seems written for newbie programmers (HTML/CSS in a programming language list? seriously? And who is, nowadays,seriously considering fortran for a new project?) and have them believe a series of opinions.
Like the cartoon at the beginning, it seems like the author is just another lemming calling for other lemmings to follow him.
[EDIT] Finished the article. It is a blatant advertisement for Scala. The support for Java sounds so false that, if Scala didn't use the JVM is would be discarded like the other languages.
To choose a language you need to make a decision based on the project first, not the language's features. The language should match the project. How big is the project? Where/how will it be deployed/run? Is performance a concern? How long should the development take? Does it have special needs? (concurrency, parallelism, 3D grphics, real-time, etc...).
