Indifference seems preferable to antipathy.
~~~
Indifference is antipathy.
We are human beings. Because of our humanity, we look at life, human experience, and even existence, with a great deal of empathy and respect.
A mathematical entity with a extreme level of awareness (note I do not say consciousness) would seem to have a great deal of antipathy purely due to it’s lack of regard for all this we would value.
Oh, and by the way, it may sound like fiction, but if there are other forms of “intelligence” outside of your universe or dimension struggling to find a way to interface, I wouldn’t put it past quantum computer to discover them. It’s one of those rare times when even a thirsty scientific mind surely must feel that knowing more is not worth it.
