This week, you're going to write about inventions gone wrong. Here's the twist: the invention in question must have come no later than the year 1980. VHS is in, the internet is out. There are no lower bounds, so feel free to write cautionary tales about mechanical timekeeping, libraries, stone architecture, pottery, agriculture, or fire. If people made it, it's fair game. Get as wild and speculative as you'd like; all genres are valid.
