The obvious bad trashy 1rst prototypes get all the hype. They always die.
A new version, the best competitor, that works, that is cheaper, better, takes the crown in the end. So obvious. No dreams, no delusions, no utopia. Just plain simple. The best cheapest functionning ones win (if the tech itself has a future which is not always the case).
