It will be called proof of person. We will also need it for proof of population, if we plan on going to another solar system anytime soon.
It will actually be more decentralized than the current government issued id`s, and people themselves will willingly upload what is needed. The system(good AI robot) will identify them, without others being able to.
I envision it within the next 10 years you know why, because people are starting to wake the fuck up, just read some on the comments on the big banker deaths, shit is coming to those who think they rule the rest of us.
There are 3 obvious flaws :
1. The AI/robots is created & trained by humans
2. If it's trained with "bad" data, then it will be "bad" AI/robots. For example, Tay's chatbot which created by Microsoft.
See https://www.cbsnews.com/news/microsoft-shuts-down-ai-chatbot-after-it-turned-into-racist-nazi/
3. Since it's decentralized, then everyone need have to copy of your personal data, which is worse than today's condition where government & company have your personal data.
