My view on the current situation of Bitcoin and the Blockchain - Joi Ito's Web

I fear that we'll build something that at the application layer looks like what Bitcoin and the Blockchain promised, but under the hood is just the same old transaction system with no interoperability, no distributed system, no trustless networks, no extensibility, no open innovation, nothing except maybe a bit of efficiency increased from new technology.

In simple terms…to engage in learning is to engage in the project of constructing and reconstructing identity.
