It's kinda weird, that most of these revolutionary technologies like AI come in waves of failure, each followed by "that will never be mainstream".
Electric cars. In Czech republic, you can see these "cars" serving around the train stations. They are still working, even though they are older then the nation itself. But still, it took nearly 30 years since their success till anyone admited, that electric cars are in fact possible market. VR started with virtual boy, and then the Oculus craze. Yet, there is still scepticism, even though the only limiting factor right now is the price.
Why is it so hard, to recognize a technology, that is just limited by price and lacking implementation? It should be quite obvious.
