I'm not so confident that Amazon will continue to have fingers in so many things in the future. I think Amazon has figured out a pretty good formula for entering product categories that are relatively new, but we'll see if they can compete long term as more focused competitors arise. That being said, their utter dominance of retail and it's vertically related industries will probably continue for a long time. But I'm pretty skeptical of AI, smart home tech, autonomous vehicles, drones etc.
