Parents sometimes disown their children, on the grounds that those children have betrayed key parental values. And if parents have the sort of values that kids could deeply betray, then it does make sense for parents to watch out for such betrayal, ready to go to extremes like disowning in response.

But surely parents who feel inclined to disown their kids should be encouraged to study their kids carefully before making such a choice. For example, parents considering whether to disown their child for refusing to fight a war for their nation, or for working for a cigarette manufacturer, should wonder to what extend national patriotism or anti-smoking really are core values, as opposed to being mere revisable opinions they collected at one point in support of other more-core values. Such parents would be wise to study the lives and opinions of their children in some detail before choosing to disown them.

I’d like people to think similarly about my attempts to analyze likely futures. The lives of our descendants in the next great era after this our industry era may be as different from ours’ as ours’ are from farmers’, or farmers’ are from foragers’. When they have lived as neighbors, foragers have often strongly criticized farmer culture, as farmers have often strongly criticized industry culture. Surely many have been tempted to disown any descendants who adopted such despised new ways. And while such disowning might hold them true to core values, if asked we would advise them to consider the lives and views of such descendants carefully, in some detail, before choosing to disown.

Similarly, many who live industry era lives and share industry era values, may be disturbed to see forecasts of descendants with life styles that appear to reject many values they hold dear. Such people may be tempted to reject such outcomes, and to fight to prevent them, perhaps preferring a continuation of our industry era to the arrival of such a very different era, even if that era would contain far more creatures who consider their lives worth living, and be far better able to prevent the extinction of Earth civilization. And such people may be correct that such a rejection and battle holds them true to their core values.

But I advise such people to first try hard to see this new era in some detail from the point of view of its typical residents. See what they enjoy and what fills them with pride, and listen to their criticisms of your era and values. I hope that my future analysis can assist such soul-searching examination. If after studying such detail, you still feel compelled to disown your likely descendants, I cannot confidently say you are wrong. My job, first and foremost, is to help you see them clearly.
