At some point in the future, there will be LLMs that will scan all voice, video, or text calls and do sentiment analysis. If they flag a call as hostile, they could send a signal to all intermediate network conduits that this person is a threat and will essentially ‘unmask’ their origin. Authorities can then take appropriate action.
If we’re lucky, laws will be passed to enable it just for cases of assholes threatening someone they don’t like. And after a few public lawsuits, the whole doxxing/swatting/death-threat thing will cease to exist.
More likely, it’ll be used by governments to stifle dissent. But you gotta dream 😔
