Earlier quoted context omitted.
It’s a tool. Used incorrectly will lead to errors. Just like a hammer, used incorrectly could hit the users finger.
There is enormous variability in how hard a tool is to use correctly, how likely it is to go wrong, and how severe the consequences are. AI has a wide range on all those variables because its use cases vary so widely compared to a hammer. The use case here is police facial recognition. Not hitting nails. The parent wasn't saying "AI is a liability" with no context.
The problem here is incidental to the tool; it was done by the cops and therefore nobody will be held accountable.
