Quote from: Miniarthe last of that should be "between two sentient beings" imo.
Two sentient beings? Why? <insert blonde joke here>
Seriously, that would greatly depend on the definition of sentient. We already know Commander Data is "fully functional in multiple techniques", and that holograms are considered sentient, though not necessarily lifeforms. But marriage?
I would like to think that we would evolve where the silly notion of marriage becomes some arcahic afterthought... we find a (soul) mate as we see fit, and thats the only definition of a union.... and why should that be defined as two BTW?
Also, if we conquer disease and aging, do we still want to be together till "death do us part"?
