As a technologist I have to point out that the technological solutions to do this *safely* don’t exist. They are at best at the research stage. ML textual analysis schemes do exist, and often misfire. These systems will need to accomplish this task perfectly and also privately.
The idea that we can deploy AI systems to read your private conversations and report crimes is frankly dystopian. Even if such systems existed, no reasonable democracy would vote for this. But this is what the EU is proposing to mandate and *build* in the next couple of years.
