For those still unaware, I am the original author of Call of Cthulhu the roleplaying game. I run my games in the 2020s, not the 1920s. Sometimes people ask me how to make games scary in the modern era. I suspect they think that cellphones and the internet, the bad guys won't have a chance.
This sees things backwards. The cultists have cell phones too. More to the point, modern technology is horrific and dehumanizing in a way not seen in the 1920s. I'm certain the King in Yellow has a TikTok feed. Our easy communication is a vulnerability - a method to more fully doom humanity.
In The Shadow From the Steeple, Robert Bloch tells us Nyarlathotep is behind the Manhattan Project. Because of course the Great Old Ones WANT us to have nukes.
In Lovecraft's tale The Dunwich Horror, Wilbur Whateley's plan to destroy the world is thwarted because he can't get his hands on a complete version of the Necronomicon. But today, the Necronomicon would be on Project Gutenberg. Every kook and psychopath on Earth would be trying out its formulae and the good guys would be completely overwhelmed.
