The people making these ought to install them in their own head to confirm whether these neurons remember any kind of suffering that may have occured.
I dont know if these will ever get banned officially, so I wonder if some tech can be made where you can install them in areas that need to be heavily "geofenced" from Meta glasses predators. Or a siren or text alerts when someone gets too close to say a swimming pool, playground or shelter with these turned on.
We all need to have somewhere safe to get groceries, go to doctor, school, shelter etc.
