I have to agree. As an example, take a look at India. They are
training a non technical society to code for foreign corporations.
Coding and debugging existing algorithms requires trainable skills like
translating written languages. However, don't expect great amounts of
innovation from trade coders unless you have worked out the underlying
principals in advance.
Just my two bits (0,1).

The following code is a PERL script capable of decoding a CSS (Content
Scrambling System) encrypted DVD in real time. This is illegal to
possess in the US according to the Digital Millennium Copyright Act, a
set of laws passed by anonymous vote in congress in 1998. The Motion
Picture Association of America (MPAA) is opposed to the distribution of
this software because it allows the owners of CSS encrypted DVDs to
exercise their long-standing fair use rights with new digital
technologies. For more information, please visit:
