I agree with you that the crypto industry in general over-hypes, and everything is a "revolution." The scalable infrastructure and developers tools still require a lot of work and getting "killer apps" is a whole new phase of traction.

With that said, I'm optimistic as all signs seem to point to the fact that security and privacy are going to become more and more critical. Facebook Libra is a great example. Even FB wants to enter this space and rightly so. They have the userbase and are trying to build a decentralized (well federated really) network. Blockstack is open vs. permissioned (Libra). We've done 4+ years of R&D work and are now in the developer traction phase. We want thousands of experiments to happen and organic usage of apps to emerge.
