AI could make you replaceable at work: Columbia business professor warns of career risk

By Jordan Keller

As artificial intelligence tools move from niche experiments into everyday workflows, researchers warn the technology could blunt employees’ thinking and originality if it’s used as a shortcut rather than a support. New findings and expert analysis suggest the biggest risks are conformity, stalled skill growth and weakened workplace trust—issues that matter now as roughly half of U.S. workers have already tried AI on the job.

Columbia Business School researcher Sandra Matz says her work points to two clear dangers when people lean on AI: professional stagnation and a slide into mediocrity. When routine reliance replaces active problem‑solving, employees risk losing the edge that once set them apart.

Why the “safe” answers are a problem

One practical reason: many AI tools favor the obvious. They surface mainstream, low‑risk responses that fit broad patterns. Over time, that nudges teams toward an **algorithmic consensus**—a sameness that dampens novel thinking and makes individual contributions indistinguishable.

A March study from the Federal Reserve Bank of St. Louis found about 43% of U.S. workers report using AI at work, underscoring how quickly these tools are reshaping daily routines. That rapid adoption has left organizations and employees figuring out where AI helps and where it hurts.

“There is a Wild West of AI use,” says Fred Oswald, an industrial‑organizational psychologist, arguing that workplaces need clearer guardrails so employees can capture benefits without taking undue risks.

Use it to speed work, not to think for you

Experts say AI can be hugely productive when it removes friction—automating repetitive tasks, summarizing information or organizing ideas so people can focus on interpretation and strategy. Americus Reed II of Wharton describes the harm when workers cede their mental effort to machines; colleagues sometimes call that phenomenon “cognitive surrender.”

AI works best when it removes routine friction, allowing workers to focus on strategy and judgment.

When AI becomes the default thought partner, the risk is that employees stop exercising judgment. Instead of treating tools as a sounding board, they let the model set solutions—reducing time spent on original insight and meaning‑making.

Early‑career professionals face a steeper learning curve. Dorothy Leidner at the University of Virginia warns that without a foundation of domain expertise, younger workers may treat AI as an answer generator rather than a prompt to learn and refine their own reasoning.

Casual use can corrode workplace trust

Drafting routine emails, Slack messages or personal replies with AI may seem efficient, but several researchers say it risks changing how colleagues perceive one another. Messages that feel outsourced can suggest lower investment and diminish interpersonal warmth.

Those small imperfections—hesitations, imperfect phrasing, even disagreements—often carry important social signals. If those signals disappear, so might some of the relational glue that holds teams together.

Leidner also cautions against relying on “digital twins” that both send and respond to messages for you; if every interaction is mediated by a model, real conversation can be replaced by mirrored outputs rather than human exchange.

Where people should focus their value

Work psychologists stress that the right response is not to abandon AI but to realign professional focus toward qualities machines struggle to replicate. Eva Selenko at Loughborough University points out a psychological cost when a tool outperforms someone on a core task: it can feel like a direct threat to professional identity.

Still, that shift can also clarify which skills matter most going forward. Reed and others argue that judgment, curiosity, creativity and interpersonal relationships will increasingly define human contribution.

  • Use AI for prep, not final judgment: let models summarize or draft, but retain final decisions and framing.
  • Protect learning time: early‑career staff should practice core skills without heavy AI assistance to build expertise.
  • Preserve human signals: keep informal, personal communication unautomated where trust and rapport matter.
  • Create clear policies: organizations should define acceptable AI uses and offer training on when to defer to human judgment.
  • Focus on nonreplicable strengths: cultivate strategic thinking, creativity and relationship management as competitive assets.

As firms integrate AI into workflows, the balance will be decisive. Left unchecked, routine outsourcing of thinking can produce a workforce that’s efficient but interchangeable. Thoughtful use—where AI removes drudgery and people concentrate on interpretation, values and relationships—keeps the benefits without surrendering what makes work human.
