Re: bestowed by some authority
Proving you are a person is something we are going to have to get used to. AI/automated methods are crossing the 95% barrier and are getting to be too hard to differentiate from authentic by normal-reasonable folks. That's text, that's voice, and that's video. Until we come up with a root of trust to use--and use it, you can't trust anything stored digital fully. Systems get compromised, files altered after they are created... really a dystopia of what we were promised the internet would do for us.
PKI/Certificates are what current tech looks like and TBH, between this and curated CRLs from a root of trust you 'trust'--This combo is something we 'know how to do' and are continuing to improve. Are there problems, sure. Far less issues with what we have now than some imaginary solution no one as fielded yet. Maybe we could eliminate SPAM texts, emails, and calls using this tech?
