Culture and traditions change over time. I don't think there will be a loss of intimacy. There will be new forms of intimacy. There will be more options. In today's world people feel pressured to marry at 30 and have kids by 35. I personally think that's a little antiquated. In the future I can imagine people being very independent, care-free, more bold, more experimental way into their 40s. If you empower people and give them more opportunities, then you'll get much more variance in how people live their lives.
