Are you ironic? Do you see what's strange in that? Machine learning isn't exempt of racism. Google has a lot of background on people, but it's generally accepted as unethic to filter undesirable people based on generalizations, even if they were statistically correct.
I think you missed the satire but you raise an interesting perspective. For example, if machine learning knows through a user's phone that they match the locations of someone who drink drives will their online persona be disciplined without their knowledge? The scenario takes a twist if that person was actually a bar worker and not a drinker. Who do we appeal to to reclaim our online reputation if all the patterns match but we are a false positive case?
I can't tell if you're continuing the jocular tone of your parent or if you're serious that this is the concern that actually came to your mind first. I charitably hope it's the first.
