Okay, Shmoopers: raise your hand if you like having a cell phone, or a computer, or being able to ride in cars or take a plane to visit someplace warm and awesome. Just as we thought—all hands are raised. Now, raise your hand if even though you like technology, you can think of some flaws? (Say, for example, cars polluting the environment, or that terrible bully on Facebook posting snarky comments about your perfectly lovely best friend.) Again, all hands raised, just as we expected.
Congratulations! You and our brainiac rats feel similarly about issues of science and technology: it's pretty cool, but sometimes there are downsides, too. So it's no surprise then that technology is a symbol of both good and evil in Rats.
Basically, when technology appears in Rats, it should always be taken with a grain of salt (and a grain of salt is bigger to a rat than it is to you): the electricity that helps you create an elevator could kill your best friends tomorrow, leaving them "all bunched together" around a motor (24.32). How's that for deep?
