> 4chan blocks the ip addresses of bad users, many services require a phone number to sign up, some sites have tried requiring a credit card, Facebook I believe uses the social graph to figure out how likely an account is to be real. Apple, Microsoft, and Google all use some combination of biometrics and telemetry data to authenticate users. I've noticed more sites requiring government ID (see LinkedIn's verification process). IP addresses, phone numbers, government IDs are all forms of outsourcing the problem of identity verification to another organization (IANA, phone company, Social Security Administration in U.S.) so we should ask if those organizations will continue to be able to effectively distinguish real humans from AÍ-powered bots armed with the ability to “deep fake” any person, using whatever tools and techniques those organizations have today. The implications seem staggering: AI bots that can collect your social benefits, withdraw funds from your bank, open lines of credit in your name. The modern economy might not be able to function if this happens. From another article: > The company’s identity technology will be important in a world where artificial intelligence raises new questions of what’s human and what’s not on the internet, [Tools for Humanity co-founder and CEO Alex] Blania said. It’s also an example of the overlap between the crypto and AI industries. https://archive.is/k5j6j https://archive.is/k5j6j
