All Advanced Aliens Are in Happiness Boxes

The problem with absolutist solutions to fermi's paradox (like this one) is that they assume all conscious entities are just like us. But that is a big assumption.

What about the sentient species that evolves an abhorrence for artificial experience? What about a sentient species with a radical minority of religious devotees who refuse the happiness boxes? (I can easily imagine that w our own soecies)

In short, it seems to me that all or most of the fermi paradox solutions require a serious lack of imagination
