AI Made Work Faster. It also Made the Office Lonelier

With input from Business Insider.

For years, work was one of the last places where Americans still regularly interacted with people outside their families and close friends. You showed up, traded ideas, complained about management, built relationships and, sometimes by accident, formed real connections.

Now AI is quietly changing that.

Daniel Deceuster, a marketing director at the nonprofit Zion HealthShare, says he used to rely on coworkers for all kinds of everyday tasks. Designers helped tweak graphics. Engineers built dashboards. Quick questions turned into conversations, and conversations often turned into collaboration.

Today, he opens ChatGPT or Claude instead.

The work gets done faster. Sometimes in seconds. But the tradeoff has become hard to ignore. Deceuster estimates he now interacts with colleagues about half as much as he used to.

“It’s sad to see that loss,” he says. “I’m an extrovert. I want that interaction.”

He is far from alone. As AI spreads across offices, researchers are starting to notice a shift in how people work together – or increasingly, how they don’t. Employees are leaning on AI tools for brainstorming, feedback and problem-solving that once happened between coworkers. The result is a workplace that can feel more efficient, but also more isolated.

Cisco found earlier this year that employees who used AI most heavily tended to trust their teams less than lighter users. BetterUp, a workplace coaching platform, reported that some workers are now turning to AI for the kind of advice they once sought from managers or mentors. Those employees also reported weaker coordination with teammates, higher burnout and a stronger desire to quit.

The concern goes beyond office culture. For many Americans, work has become one of the few remaining social institutions left standing. Church attendance has fallen. Civic clubs faded years ago. Fewer people join community groups or even know their neighbors well. Work filled some of that gap, however imperfectly.

AI threatens to thin out those interactions too.

The irony is that office technology originally moved in the opposite direction. Email, Slack and Zoom made it easier for people to collaborate constantly. White-collar jobs increasingly depended on teamwork, feedback loops and shared expertise. The modern office became deeply social, even when people complained about nonstop meetings and endless notifications.

AI changes the equation because it gives workers another option: bypassing people altogether.

Large language models are available instantly. They never get annoyed. They never take hours to reply. You can ask the same question ten different ways without worrying about sounding needy or uninformed.

That convenience is powerful. It is also reshaping professional relationships in subtle ways.

Even workers who embrace AI are starting to question what disappears when everyday interactions fade. Fewer casual conversations can mean fewer opportunities to learn from coworkers, navigate disagreements or build trust. The tiny moments people barely noticed before – asking for help, brainstorming ideas, venting after a frustrating meeting – often held teams together.

Some executives argue that less interaction is not entirely bad. Offices have become overloaded with meetings and interruptions, and AI can cut through a lot of that noise. Peter Pang, cofounder of AI platform Creao AI, says his company now spends far less time arguing internally because AI agents handle much of the workflow.

Still, researchers warn there is a difference between reducing pointless friction and stripping away the human glue that makes workplaces function.

Jessica Reif, an incoming Wharton professor studying AI and teamwork, says companies risk turning offices into places where people simply “combine inputs” rather than genuinely collaborate. Faster output does not automatically produce stronger teams.

Some businesses are already trying to avoid that outcome. Instead of using AI to replace interactions, they are experimenting with ways to support them. Workers use AI to prepare for difficult conversations, draft sensitive emails or practice negotiations before talking to colleagues. Others are rebuilding social time more intentionally through mentorship programs, retreats and more frequent one-on-one meetings.

That may become increasingly necessary as AI tools get better.

The workplace has gone through this kind of adjustment before. Remote work during the pandemic forced companies to rethink how employees stayed connected. AI could trigger another redesign, this time around how people maintain relationships in offices where fewer tasks actually require another human being.

For now, the shift is still unfolding. Many workers are enjoying the productivity boost while only beginning to notice the social cost.

The danger is that offices become quieter without anyone fully realizing what disappeared. Work may become smoother, faster and less dependent on other people. It may also become a lonelier place to spend most of your waking hours.
