Startup Idea : Improving the Khan Academy

I think the Khan Academy is probably the next big thing in education. It will fundamentally and dynamically aid the way we learn. Yet, some will state that even though it will be a huge leap forward, the presence of a teacher is still indisposable. Well, lets develop an interactive hologram to go with the Khan Academy. Holograms are availble in its basic form (Tupac Hologram performance) but its quite possible to bring to an enhanced level with funding and guidance. This development wouldn;t stop at education; it could be a buddy to talk to, exercise with, etc. Once the tech is perfected, I would even conduct a study to see if it helped alleviate depression.
