I think the ideas you expressed here are true for an (individual) professional who works in any field that lets him/her retain his/her individuality. (IMO some jobs like programming and writing have more chances for ‘retaining of individuality’ than some other jobs like airport security and tailor-guy-in-a-sweatshop. Some jobs only let a few people to be individuals, like cooking: 1% people are chefs at great places, the rest work shifts at soup kitchens)

Even the links you provided are more about normal (aka non-programming) jobs.

p.s. I am not a native English speaker, so excuse me if something I wrote offended you. In that case, I did not mean it.

Truth be told even the Syntax is somewhat transferable.

I guess all my programming experience in java, my OO concepts and architectural tricks didn’t matter when I had to develop a full featured application in C++ with Qt, or the sites and tools I’ve built in python.

All programming skills are transferable, whatever I know already gives me an edge on whatever other technology I use, and using different technologies keeps you refreshed and learning new ways of using the old tools you already know.

All languages you put on that table are transferable skills bro.
