The Hidden Cost of AI: Overworking and ‘Brain Fry’ in the Modern Workplace

Artificial intelligence (AI) is rapidly transforming industries worldwide, promising to streamline tasks, boost efficiency, and reduce human workload. However, a growing body of evidence suggests a paradoxical effect: for many employees, AI isn’t easing their burdens but intensifying them, leading to increased stress, cognitive overload, and a phenomenon scientists are calling “AI brain fry.”

The Paradox of AI: More Work, Not Less

Despite the rhetoric of AI freeing up human capacity, over half of employees who regularly use artificial intelligence report an increase in their workload. This heightened demand often results in significant cognitive strain, including difficulties in concentration, decision fatigue, and an overwhelming influx of information.

Kasia, a public procurement specialist, shares a common frustration: “Analyzing documents was my main professional skill, and today I hear from my boss, ‘just feed everything into ChatGPT.’ The worst part is I still have to double-check everything after it, which significantly lengthens the entire process. Every error impacts subsequent project stages, and there can be many of them.” This constant need for human oversight, even when AI performs the initial task, adds layers of work rather than removing them.

Wiktor, a journalist, echoes this sentiment: “The more I use AI at work, the more I feel like I’m the robot here. I’m using more and more AI, and when I don’t, I wonder if AI wouldn’t do it better than me. It frustrates me to think if I’m truly needed in all of this.”

AI Integration Across Industries: From Fast Food to Healthcare

Artificial intelligence is already a daily reality in many sectors, intended to simplify work, accelerate processes, optimize tasks, and provide assistance. It has even permeated professions that, at first glance, don’t seem to fit the dynamic pace of technological development.

The latest EY “Work Reimagined Survey” reveals that nearly 90% of corporate employees worldwide use AI in their daily work. The application of AI varies widely, influencing the number of tools used, the extent to which AI replaces or complements human tasks, and the level of supervision required over algorithms.

  • Data & Content Generation: Fifty-four percent of surveyed employees use AI for data retrieval, and 38% for summarizing documents. Beyond this, AI is a powerful tool for analysis, research, generating text, graphics, and design.
  • Creative & Specialized Fields: Klaudia, a cosmetologist, found AI helpful: “ChatGPT created a recipe for pre-made eyebrow tint mixtures for me. I had trouble matching the right color, and another time it gave good advice on how a cream works.”
  • Healthcare Challenges: Marta, a family doctor, faces a different kind of challenge: “Patients now come in ‘diagnosed’ by ChatGPT and don’t want my help. They expect me to prescribe the medications recommended by artificial intelligence.” She recounts an instance where a patient demanded a medical certificate based on AI’s advice, overriding her professional opinion.
  • Corporate Implementation: Companies like Burger King have introduced advanced AI systems to monitor employee etiquette, checking if staff say “please” and “thank you” frequently enough. Tech giants like Microsoft and Shopify openly encourage employees to delegate tasks to AI tools, while Meta uses the number of lines of AI-generated code as an engineer performance metric.

Supervising AI: A New Source of Mental Strain

The continuous interaction and oversight of AI tools have given rise to a unique form of psychological fatigue. A group of researchers described this phenomenon in the Harvard Business Review, terming it “AI brain fry”—a type of mental exhaustion resulting from excessive use or supervision of AI tools. Respondents often compared this feeling to a mental fog or a “buzzing” in the head.

Symptoms of AI Brain Fry include:

  • Difficulties in concentration
  • Slower decision-making
  • Headaches
  • Increased errors
  • Decision fatigue
  • Burnout

The study found that supervising AI proved to be the most psychologically taxing. Respondents whose work required significant AI oversight expended 14% more mental effort, reported 12% greater mental fatigue, and experienced 19% more information overload from the data they had to process.

Francesco Bonacci, founder of Cua AI, a platform for creating custom AI agents, summarized this sentiment in a viral post on X (formerly Twitter): “Infinite productivity destroys the brain.” He elaborated, “I end each day exhausted – not by the work itself, but by managing it. Six open work directories, four unfinished articles, two ‘quick fixes’ that led to rabbit holes, and a growing sense that I’m completely losing the plot.”

Many workers experience AI brain fry as an inability to think clearly after a full day of AI use, akin to a mental hangover, characterized by difficulties in concentration, slower decision-making, and a powerful urge to step away from the computer to “reset.”

The Psychological Toll: Feeling Replaced and Overwhelmed

Beyond the cognitive fatigue, AI also introduces existential questions for many professionals. Kasia, the public procurement specialist, reflects on her future: “I don’t feel it yet today, but sometimes I think about my future. Because if, until recently, I had to analyze documents, and today the director says AI should do it, then is my position even necessary?”

Journalist Wiktor shares a similar concern: “Am I truly necessary in all of this?” This growing uncertainty about one’s value in an AI-driven workplace contributes to feelings of frustration and disengagement.

Marta, the family doctor, expresses a profound shift in her role: “Professional burnout is perhaps too strong a term, but this isn’t how I imagined this job. I wanted to help people, but patients increasingly bring in printed ChatGPT diagnoses. I can see the distinctive font, the bullet points. They don’t want my help at all, and I feel like just a ‘pen’ to sign things.” She finds herself competing with instant AI diagnoses, losing the most engaging part of her profession: “The greatest satisfaction in a doctor’s work is when I can help a patient. Sometimes I have to act like a detective, connecting the dots – patient interview, checking test results, comparing. AI-‘educated’ patients deprive me of the most interesting part of this job, because these diagnoses aren’t always wrong. A doctor needs time to draw certain conclusions; AI does it instantly. But I don’t want to compete with artificial intelligence.”

Who is Most Affected by AI Brain Fry?

The impact of AI brain fry is not evenly distributed across all professions. Data suggests certain roles are more susceptible to this new form of cognitive exhaustion:

  • Most Affected:
    • Marketing departments (26%)
    • Human Resources (HR) (19%)
    • Operations (18%)
    • Developers (18%)
    • Finance and Accounting (17%)
  • Least Affected:
    • Product Management (9%)
    • General Management (9%)
    • Legal Professionals (6%)

These disparities highlight that the nature of AI interaction—whether it’s generating content, supervising processes, or informing strategic decisions—plays a crucial role in its psychological impact.

Conclusion

While artificial intelligence undeniably offers powerful tools for innovation and efficiency, its unchecked integration and the increasing reliance on human oversight are creating significant new challenges for employee well-being. The phenomenon of “AI brain fry” underscores the critical need for organizations to implement AI thoughtfully, prioritizing human-centric design, providing adequate support and training, and fostering a culture that values human contribution over mere machine-driven productivity. Without careful consideration, the promise of AI to lighten our loads may instead lead to a future where many feel overworked, overwhelmed, and ultimately, replaced.
