This is why most EdTech is just a clever tool or a nicer content. The trouble is - the rhetoric of other sectors have been borrowed, and often, one meets people with one tool that claims to solve all problems. Like market size projections such a pitch is simple, and utterly misguided. And, like all those new labels and market size projections, this ensures a bubble, the creation and invariable bust of unreasonable expectations.
So, yes, EdTech is bust. The investors are already cautious, and the next global economic wobble will make EdTech companies tank completely. One can be certain that a new label, and more market size projections, are in the works. It is time to get into the new boat, as the flood is coming.
