Trust is more complex then we take credit for.
Even when it comes to people like our parents, there are things we would trust them to do, and things that we would not trust them to do. But what happens when you have zero trusted elements in a category?
At the end of the day, the digital world is the real world, not some seperate place 'outside the environment'. Trying to treat digital like it doesn't exist puts you in a dangerous place to be deceived. For example if you're looking for XYZ and you manage to leak this into the digital world, said digital world may manipulate your trusted friends via ads, articles, the social media posts they see on what they think about XYZ before you ask them.
