I predict capsule networks will not nearly have as big of an impact on the ML community as many think it will. Why? Because the main reason they exist is to address performance issues in really advanced, cutting-edge, models. But that is not what drives upvotes here and on reddit. The failure of capsule networks to pick up steam and the continued popularity of GANs, I think, is a signal that the main reason ML is still trendy and in vogue is because the subject, AI, tickles the imagination of engineers, but is still, five years after ML started to become popular, not as big in actual practical engineering systems as what the outside public might think it is.
