@jennymackness I was happy to read you here also
I do agree with @downes on the (possible) multiplication of educators, especially when looking at the broad spectrum of educator opportunities. In one of the MOOCs I collaborate on, the MOOC is used as a first step for professionals (start-ups and SME) who then move to the opportunity to be coached in small groups for specific, very specialized content. The idea being that through this contextualized and personalized approach, their success rate will increase, and their networks grow. In that sense I fully agree with your mention that educators must definitely have experience, and that experience in a particular field is the best way to be able to 'feel' that field in terms of necessities, priorities etc.
Now... sharing my two cents, and - warning! - this idea comes from wild and free dreaming...
I feel that most jobs in the next phase will be transformed into automated jobs (some of the stuff legal people do can be automated, grading papers will become more automated, building houses will become more automated - including the full 3D-printed house). So, while resting I think to myself, what could this mean. To me, this means we need to prepare for the next Age of humanity. Which can be seen as dark and somber, or wrapped in a pinkish hue of optimism (and probably somewhere in between). Maybe it is like Moore's law, and the Age of human is increasingly shifting from one age into the other: Industrial age, Knowledge age... Leisure age? Why should not we build a society where production and labour for money is transformed to being able to lead a fulfilling, leisure-based life? In that case, all 'jobs' will stay, but it will no longer be necessarily linked to money (the jobs), it will be driven by passion, willingness and interest. In that space, we - as educators - will thrive, I am sure.
