Finally, also, there is the question of technology. I get the feeling that most companies talking education innovation focus on technology not because technology builds a better education proposition or that technology is the only way to achieve 'scale'. The reason they use technology is because their business templates, and that of their investors, are built around technology business models. The effect of this is that they seem to throw technology at problems which can be done better through human intervention, and where, technology, with all its army of know-it-all consultants, actually costs more and creates poorer solutions. In education, the more successful (and sustainable) businesses have actually built around human support and interactions and a fairly old method called franchising, and any of the technology-based disruptors are yet to match the success of those models. One could say that they are indeed playing Uber - making a long bet for the day when technology-based education becomes the norm - but I am not sure these companies would last the bursting of the inflated private valuations, which will inevitably happen when money starts becoming tighter.
This is an example, but consider the success of companies which offer University Preparation or Study-Abroad Solutions, and do it in a people-intensive manner, in conjunction with existing institutions and within regulatory framework, and some absurities of the education disruption talk should become obvious. On this, I rest my case on building platforms, enabling the current education system meet the emerging expectations and serving the learners better.
