Almost-FAI insists "death is bad", human life has positive value. Other aspects of ethics are also gotten right, but personal choice and suffering avoidance is underrepresented.

As a consequence, almost-FAI makes copies of you and keeps them alive in the minimum resource state needed to keep you alive and safe, which spells billions of years of boredom for millions of copies.

Alternatively, CEV-FAI takes the world religions too seriously and implements hell for various sins.

Alternatively, some equivalent made by a ruling class of "moral" humans with longevity technology, possible even without AI.
