As a kid, I read S. J. Revich’s Ibrahim the Magician and tried rationalizing some of the tricks. Later on, I realized the silliness of doing so. The author didn’t necessarily have an explanation for the tricks he described. That’s not his responsibility. He’s like the rest of the audience, who is just amazed at the feat.
Same here. As long as it doesn’t get in the way of the plot, the author can employ technology without knowing how it works, and then he can be just as amazed as his audience.
