Digital Aristotle for Everyone

An interesting talk from C. G. P. Grey on how the internet may influence education. Of particular note is the software angle, and the projected reduction in the numbers of teachers (which I personally find disquieting). I want a future where technology helps supplement interpersonal education,  not act as a replacement. The claim that this would be awesome news for both students and society I find overly sweeping/ generalising. The teachers you interact with I have found to be the formative core of education (hopefully good). I feel that we would be loosing a great deal by claiming such a role to be on the precipice of obsolescence. Until testing methods become sensitive to a much much greater degree (to the level of true artificial intelligence/ singularity), I would prefer to have a person as my educator, rather than an artificial personal one.
