You might want to have a look at a course called "Mindshift" on Coursera. It is free to access and the main topic is the combination of lifelong learning and career switching. https://www.coursera.org/learn/mindshift From personal experience I would say: you will be more successful in such a career change, when you do not ignore the skills you have for your current job, but find a way to use them in the new one.
Org is part of a standard Emacs install since version 24.
Same feeling, especially with the number of Org users that are not programmers, but just writers. There has been a time for me, when I used vim for programming and Emacs with Org Mode for structured texts, like essays and articles, so I can imagine there being a lot of people outside of the CS and dev bubble enjoying their Org Mode and not being counted by any survey.
We also still have that in current Seamonkey: https://www.seamonkey-project.org/
Strange headline. Last time I looked at a map, Brazil was part of America. Where else would they look for Sperm? Asia, Europe? (Of course I read along and even before knew they meant the United Stated, but America is not the United States.)
