How do we verify/trust chain of custody of, idunno, "Mark Zuckerberg calling for the killing of all lefthanded people"? What I think will happen is that it'll be like what we have now but worse: some podcaster will make an offhanded remark about Mark Zuckerberg "saying some horrible stuff about lefthanded people" causing frantic TikToks about that it means killing lefthanded people, all based on a supposed "secretly recorded video" that no one can validate due to all of the noise.
