The problem with understanding trends is that people naturally tend to think that the past predicts the future. What they forget is that what goes up, usually goes down. This is true in the vast majority of cases except for certain occasions (rise of internet, mobile, cloud). This is why hype such as 3d printing, VR, AI, IoT, chat bots, are just that -- hype, until we arrive at the point in time where the exact necessary breakthrough occurs for each, but I don&#x27;t see it yet in many of todays cases.
