Writer Storm - A Brainstorming Community

I find the idea of some sort of machine non-purposely blocking magic to be kinda silly, honestly. If it was something like 'the extra pollution in the air from industry makes it more difficult for magical energy to flourish' or 'with scientific advances people were less likely to believe they had magic' or 'there's a set amount of magic and the higher the world's population the less there is for everyone until Highlander effect kicks in' or even 'fluoride was added to water to dampen magic' I could buy, but 'the printing press was invented and magically got rid of magic' would take a lot to be believable.
