When I was a teenager, and computers where just starting to become common things in Italian households, I remember a family friend used to be convinced that they could transmit viruses that where dangerous to people.

What happened is that he probably heard about computer viruses, and he just stuck to his own definition: viruses are a danger for human beings.

This challenge in making new ideas fit into old mental concept and ideas is very common. And if you fall into that, you are not an idiot or uneducated. You simply still have not had the mental shift.

And for that, you are pretty much always in time.
