In the old days, it was sufficient to know how to write code in machine code or in FORTRAN, or, heaven-forbid, COBOL in order to make a good living working at a desk in an air conditioned building. Then, along came C, and C++, and Pascal, and BASIC. Sure, some folks used LISP and SmallTalk, but they were pointy headed academics or underpaid grad students.
Now, you need to know all of those, and Perl and PHP and Ruby and Erlang and Scala, and who knows what else wil get invented this week. You practically need a second page for your resume just to list them all, and you’ve made O’Reilly rich buying those stupid animal books for whatever new language some drunken grad student dreamed up.
Our pills can help. When folks ask “Do you know ___”, and name some language you’ve never heard of, just say “I take ‘Language Learner’ pills; I’m can pick thet up in an afternoon.” It’s not true, but the folks hiring you don’t really care, since you’ll be actually writing all your code in C or Visual BASIC anyway.
