I know a lot of people will want this to be true but it's not. I've been inspired by various people over time: John Lennon. Doug Gilmour. Neil Young. Arsinio Hall. Jose Bautista. These are my role models. These are (among others) the people who inspire me. Not one of them is a teacher. Ergo, one does not need teachers in order to be inspired. I don't think that the field of education understands, in general, how much of what it does is also done by parents, role models, friends, professional associates, and more. If the core function - to teach - can be performed by a machine, then the ancillary functions - motivation, inspiration, socialization, etc. - can be performed by everyone else in society. And, indeed, should be performed by everyone else in society.
