If people lean on AI more, are they quietly working alone more and teaming up less?

This explores whether people who lean heavily on AI end up working alone more and collaborating less. No study here directly tracks how heavy AI users split their hours between solo work and teamwork. Several notes come at the question from the side, though, and together they suggest that AI can take a collaborator's place without anyone deciding it should.

The clearest signal comes from science. Researchers who use AI publish about three times as many papers and get nearly five times the citations. Across the whole field, though, collaboration between researchers falls by 22%, and the range of topics people study shrinks Does AI help individual scientists while narrowing scientific focus?. Individuals gain while the shared enterprise narrows. A field experiment at Procter & Gamble shows how that can happen. Single professionals working with AI produced solutions as strong as two-person teams working without it. AI also helped people reach beyond their own specialty, a job a colleague from another department would normally do Can generative AI replace the benefits of having a human teammate?. If one person plus AI matches a pair, the push to find a partner gets weaker.

The less obvious finding is about what solo work feels like afterward. In four experiments, people who had collaborated with AI felt more in control when they went back to working alone, but they were less motivated and more bored. AI had taken over the engaging parts of the task and left them the routine leftovers Does AI collaboration drain motivation when workers return to solo tasks?. A related argument says AI shrinks the hands-on execution layer of knowledge work, while deciding what to do and delivering the results stay the same size or grow Does AI really compress all layers of knowledge work equally?. That may be where human collaboration ends up concentrated. Secrecy may also isolate people: most workers in one large interview study hid or played down their AI use because of stigma Why do workers hide productivity gains from AI use?. That makes AI a private side channel rather than something a team shares.

Not everyone treats this drift as inevitable. Microsoft's research framing argues that the next frontier is team productivity, meaning AI built around shared goals rather than personal assistants. The note points out that this is a design goal, not yet a measured result Can AI boost how teams work together?. At a smaller scale, writers sharing a document preferred editors that showed their partner's AI prompts. Making AI use visible helped them understand how their co-author was thinking, though full transparency made some of them self-conscious Do writers want to see each other's AI prompts in shared editors?.

The corpus doesn't settle whether heavy AI users spend more time working alone. What it does suggest is that AI as currently designed is a one-person tool, and when it works well it can quietly do the job a teammate used to do. Whether collaboration shrinks may depend less on the users than on whether AI tools are built to be shared.
