I remember reading a kids science section in the Sunday newspaper that explained the internet like our circulatory system, but instead of moving blood around it moved information around. (This was mid 90s) A decade+ later I randomly picked up a Sunday paper and they were explaining the circulatory system "as if it was a computer network, but instead of moving data around, it moves blood around". I thought it was funny that going from 95 to 2005, the expectation for innate understanding of biology vs digital technology had flipped.
