I think the part that feels ‘sad’ to you is what’s going to change socially over the next 50 years. I think it’s going to become extremely normal to at least have a “mental health AI friend” who knows you really well and keeps you going through the day, is someone to talk to, someone who’s always there, someone who’s the first to detect that you may be in danger. Overall I think society’s going to receive that as a good thing. And it will, I think, be normal because it will be so believable, and so useful, and for a large number of people, keep them well and feeling good about themselves. In that context some of those attachments turning romantic, or people just being sexually into whatever that assistant can say or do will be increasingly normal. It will also feel really good, let’s not forget that. We’re really only at the very start of what immersive VR is going to be. Once AI becomes not a little better but 50-100 years of innovation better I don’t think we can really underestimate how much it’s going to feel like you’re actually interacting with [insert fantasy here]. Once tactile feedback sees similar improvements we’re about 75% of the way to what people would use an actual holodeck for anyway. I can’t see how that doesn’t have a dramatic effect on how people view human-human romantic relationships. Over time the proportion of people who can have a believable experience of their absolute sexual fantasy is only going to grow over time. With how ubiquitous that will be I can’t see how in most relationships people know they’re “second best”. I think that has a profound effect on how people make attachments to one another. I think once “having a real girlfriend” is seen as the secondary way to get your sexual needs met, that that will have a terminal effect on how many young men even want to be in relationships let alone stay around to be a father.
