However, if you are talking about Blockchain technology and applications beyond currency and gambling, there may be something onto it. For example, check out Ethereum:
This allows you to enforce and reward contracts in a very flexible and completely decentral fashion. Also, "agreeing on one truth/history" has been replaced from "power of work" (arms race to burn energy resources) to a more subtle decentral reputation system. This is more about finding consensus among the network participants as intelligent individuals, rather than who's able to invest more energy/hardware resources more quickly.
Creative stuff like Ethereum has not just the potential to replace payments, but enables companies that are totally differently structured than what we find today. If that's for better or worse, I'm not sure.
But if there's any justified hype about Bitcoin, it's about emerging projects like that - not about Bitcoin itself.
