If everything becomes unlocked by a block chain secured by cryptographic keys, people and everything we use must evolve to embrace cryptographic keys as digital identity.

Every time the topic of digital identity is raised, there is backlash. The reaction is ill founded. Resistance should be to digital identities that are issued, controlled, and revokable by centralized authorities (government, corporations); with authorization for services being programmable by authoritarians (i.e., social credit).

We need to embrace decentralized digital identity, which is what Bitcoin uses, where the end user arbitrarily issues their own keys, and then maintains custody and control over their keys, never relinquishing secrecy to anyone else. That is Self-Sovereign Identity.
