"some random stranger in a remote datacenter going through some spinning disks" is too hard to correlate for average people. This is an invisible threat to them

"some random stranger in a remote datacenter going through some spinning disks" is too hard to correlate for average people. This is an invisible threat to them. If I give the person in the example a name and face, e.g. "Officer John Smith living next door and you talk to him everyday", they usually immediately become more vigilant. I imagine that if the covid droplets in the air are visible, we would have a much easier time convincing people to wear masks in the beginning of the pandemic.
