This is precisely why this discussion is best never had. It’s nonsensical. It’s the stuff sci-fi writers come up with because reality doesn’t allow for it. You cannot in any way discuss any part of this subject with a straight face because it is all made up inside your own head. Everything that you think you understand, or feel, is made up solely to justify your argument. There’s no facts here, only ”vibes”.
Empathy is essentially feeling the emotions of others, they need to have emotions in the first place.
