Lord Puttnam said something every interesting at an E-Learning Foundation Conference. Having been a film producer, he said that up to about ten years ago, to be a successful cinematographer you had to be able to take a camera apart and put it together. Now, none of those sort of skills are required: you need a whole different set of skills in order to find employment in that occupation.
I believe a similar thing is true in the realm of “digital education”. Almost nobody needs a gasp of computer programming, and even fewer need to know how computers actually work.
