Having been addressing the future of education lately, and studying the advances in technology, pointing at the experiments in Germany about 6-people working being in remote places but working together live in 3D enabled by virtual reality, the first commercial application of a simpler version is live already. A major hotel chain started the (expensive) option to beam in a 3D hologram version of a person (e.g. the executive of a company) in a meeting live. Technology goes fast, even faster that I thought. Avatar teachers, coaches and tutors as well as bionic brains may be around the corner, instead of appearing in 2030, what I expected before.
