Americans are spending more time alone, marrying less, and making fewer friends. Many adults report feeling isolated, left out, or lacking companionship, and research estimates a substantial share experience moderate to severe loneliness. Studies of meaning and nostalgia show that the most powerful memories center on other people, being cared for, showing up for someone else, and belonging to something larger. Loneliness and nostalgia are closely linked, and nostalgia reveals that connection depends on mutual conditions where people matter to someone and that someone matters back. The rise of generative AI companion apps and AI-based therapy is growing rapidly as a proposed solution to unmet social needs.
"Americans are spending more time alone, marrying less, and making fewer friends than in previous decades. And it isn't going well: A 2025 American Psychological Association survey found that around half of adults report feeling isolated, left out, or lacking companionship. Academic research suggests that around 37% of Americans suffer from moderate to severe loneliness."
"My research on nostalgia, the bittersweet longing for the past, revealed something that surprised even me: the memories people return to most powerfully are almost never about personal achievement. They are about other people. Being cared for. Showing up for someone else. Belonging to something larger than themselves."
"Loneliness is one of the most common triggers of nostalgia, and nostalgia reveals what true connection requires: conditions under which we matter to someone, and they to us. What I've learned is that Americans are not simply short on social opportunities. They are losing the conditions under which genuine human bonds form and hold."
"According to a report published in Harvard Business Review, therapy and companionship is are now the number one use case for generative AI-up from number two the year before. The market is growing fast. Downloads and revenue are up sharply, and new AI companion apps are launching at a rapid pace."
