What an interesting read Jill, I'd never heard of these positions.

You piqued my curiosity and I came across something that made a lot of sense:

“These are jobs that probably only 500 people could do right now, so there are these insane salaries...But in six months, 50,000 people will be able to do that job. The value of this knowledge is greater today than it will be tomorrow.”

Watch this space I guess...
