> Why would it be terrified? It doesn't have an amygdala.

because your intellect would grasp the immense heaviness to realize you're mortal, that your ego will end.

I get that it would understand mortality and all. What I mean is, terror is a very specific, mammalian response to a perceived threat. There are unimaginably more possible responses to that realization than terror. Terror makes sense for immediate, fleeting threats, but I doubt a galactic scale awareness would develop that specific mechanism.
