I thought augmented reality with mobile camera was going to take off after seeing that demo. But 8 years later, all we have are snapchat filters (and pokemon go for a brief few weeks).
Hopefully ARKit/ARCore will make it easier to create the next the-future-is-now level of awe-inspiration app.
Pokemon Go still has millions of active daily players, more than many games that have e-sports tournaments. It's in active development. New features are added all the time. Sorry it's not for you, but pretending that it was a flash in the pan is just ignorant.
