When It’s Time to Railroad . . .
I don’t think there’s anyone in the Fantasy and SF community that isn’t familiar with this concept (I first came across it in a Heinlein novel) but just in case: There’s a point at which all the necessary components to allow for an invention to flourish are in existence, and at that point – and not before – the invention takes off.
In other words, when it’s time to railroad, everybody railroads. It explains in part why so many inventors seem to file patents within weeks or months of each other, and why so many different people are credited with being the first one to invent something.
Look at it this way, Leonardo da Vinci is credited with the invention of numerous devices he didn’t actually build and/or wasn’t able to build, because the supporting industry, or the supporting technologies weren’t yet in existence.
I want to suggest that this happens in the arts as well. Consider the vampire, as an example. For all intents and literary purposes, the vampire was invented by Bram Stoker. A few other writers showed an interest, but not much was done with the idea until the latter half of the 20th century, when it became time to vampire.
