Templates and Scripting
Oh man, I love and hate this topic.
Studying history for so long as taught me that humanity tends to do the same things, like the same things, and fall into the same traps over and over. I don't think there's anything nefarious there - people are just the way they are, and human nature puts the collective into similar situations again and again.
When it comes to entertainment and celebrity, it starts to my skin crawl. I mean, I understand story templates and things like that - the hero's journey or enemies-to-lovers stories or other tropes are always going to be in play. But those templates are popular because them mean something and speak to something essential in the human experience.
But celebrity clones, every movie being the same, and reality being influenced by sci-fi (most sci-fi stories are warnings and allegories, for goodness sake!), is truly repulsive. With how thoroughly vast life is, are we really saying that these small slices are the only ones worth representing? Or are they just the ones that people think will make the most money the fastest? And with how much weirdness the internet has given us access to, how has our culture managed to homogenize even more? It boggles my mind.
