Ben Woo takes exception to a Gartner analyst saying that Big Data is now in the “Trough of Disillusionment”. The nub of his argument is that where you are on the hype curve depends on how the hype curve plays out in your domain.
I think the hype curve is an interesting idea, but it's intended to remind us about the psychology of change, rather than necessarily guiding our investment choices. Also, the trough of disillusionment on one hype curve may create an opportunity for interest in another innovation. We need to remember that hype is about inflating expectations, and allow for both boosterism and disappointment in our technology decisions. Neuralytics
