Unfortunately, for common people whose aim is not celebrity, this means handing over your privacy in order to have a voice.
We can do this in our IRL circles of trust, people know you because they have met or interacted with you personally.
Online, this means someone like Zuck creating a digital identity for us after we entrust them with our privacy, or some kind of open source complicated technology identifier like a cryptographically verified signature that is techno bro-free that will only be adopted or understood by tech literate.
It's a dark day for genuine human interaction and trust.
