Okay but have you ever seen a dead body? There is no energetic feeling at all, it’s just an inanimate object at that point. Most people who see dead bodies are not afraid from seeing the dead body, if they are afraid it might be because they’re wondering how the person died and if they themselves might be in danger.

Diseased bodies, yes, I remember when my son was really young, maybe 1-year-old, he got a scary flu and the look in his eyes was uncanny and it was terrifying, that alerted me something was very wrong. Thankfully he recovered, that was 20 years ago, he’s fine.

Competition from other hominids and genetic disease.

Or, more likely, just the Uncanny Valley not being that big of deal in general.

It’s fun to meme about it but it’s not like people are running screaming from the theater because the CGI was off, it just doesn’t look right sometimes and our brain doesn’t like it because it doesn’t fit the patterns it’s had reinforced over a lifetime.
