Fair points all. What I read was that he'd prefer more hands-on (i.e. watch me do the craft) types of presentations, whether at school or academia, rather than didactic rules to follow or some other form. This is one type of instruction and I think it can be useful to see more of it. Nevertheless, I don't see a particular shortage of such how-tos and I think there's room for multiple types of instruction. As the author and commentators seem to agree: there is no replacement to practicing it to actually learn how to do something.
