P. T. Barnum just turned in his grave! He said USEFUL! If you said "learn to write SQL instead of abstracting stuff through a framework" or even "learn to mix cement and lay formwork" - THAT would be useful.
Erlang, Scala (or dare i say it), Lisp - possibly not so much 'useful' as an academic pursuit.
Interesting thing for me personally is that I have often wanted to read an updated - so to speak - version of that fine little book by Barnum.
