[Question] Why do we choose to add humans but not bugs?

With the following assumptions, if we aim for increasing total utility, why would we still choose to design a future with many humans instead of many many bugs?

  • Sentient animals’ well-being matters. (Even with fewer utility.)

  • At least one kind of bug is sentient.

  • Well-being in animals can be positive.

  • It will be possible in the future to create and sustain an artificial environment through a dedicated AI, where bugs will thrive, especially considering that future bugs may be digital beings.

  • Humans or similarly complex intelligent beings are immensely more prone to pain than bug-like beings.
