- Social interactions are being transformed by rapidly advancing digital technologies. Over the next decade, interactions will increasingly occur online rather than in-person as distances are compressed.
- By the 2020s, remote work and digital communication may replace much physical interaction in both social and professional settings. Digital identities and avatars may become the primary way people represent themselves and socialize online.
- Emerging technologies like artificial intelligence and robotics may further reduce the need for human labor and physical activity. If machines develop human-level intelligence, people may interact as much with technology as with each other.
- While technology will likely improve many aspects of life, its growing influence could also threaten in-person connections and exclude those without
