Re: Marry a laptop?
Marriage has served many purposes. Which purposes these are has varied throughout history. There are certainly many couples who married without love in order to secure alliances between powerful families, but there are also people who gave up much of their wealth and status to marry someone beneath their class whome they loved. Even the occasional royal marrying a commoner.
The importance for child-rearing is somewhat lessened today by the availability of contraception. It is no longer an inevitability that every sexually-active heterosexual couple will produce children, as used to be the case, so there is no longer that need to force them into a long-term legal union to make sure they would have no choice but to combine resources to care for those children.
