Whenever people imagine virtual something, they sometimes put it at odds with the physical incarnation of it. That is exactly not what we imagine when we think of Khan Academy. When we think of Khan Academy, yes, if you have nothing, if you are a villager in some rural part of India and you have no school, hopefully we can get a device out to you and then get you access. We can help you learn and move up your knowledge edge.
But the ideal is you have a physical environment. You have inspiring mentors and adults and teachers around you. You have your peers around you in a social environment. And in that context, we see ourselves as a tool to enable really personalized instruction. That ability to move to a competency-based model as opposed to a seat-time model, that ability to move to a differentiated model as opposed to a one-pace-fits-all model is really a necessary ingredient to actually moving the dial. At the end of the day, we are a tool to empower teachers. And it is up to the teacher to decide how that tool is used.
