Wow, the think of the children lines are so overused, I wonder why they aren't obnoxious for regular folks. And I'm a father of a 4-year old and I can really understand the natural urge to protect children from pedophiles, but this is becoming ridiculous, plus as a father I also don't want my child to grow up in a world in which he has no privacy rights. If a device for reading one's mind would be invented, it would instantly be used by government agencies, because investigative opportunities and if law enforcement could do that, than so could criminals and oligarchs - yet our laptops and phones are an extension of our mind and we really aren't far from such a dystopian future.
These people act as if this technology existed since the dawn of men. What on earth did people do before being able to snoop on our digital footprint? And is there any evidence that these investigative opportunities are lowering criminality or are we talking hypothetically?
