IMHO, these things are just going to be craze and hype and then eventually will be forgotten and replaced again by another one once we're done with the bull run. What excites me is their contribution to the bull run but after that, we're going to see on how they'd be ending up just like the NFTs and other project types that have been in the market last bull run. There are too many of them and it becomes different whenever we're approaching to the next bull run. So, this time it will be them that you've mentioned but next bulls, it will be different.
