Take it from anyone who's ever worked in management: Humans can be dumb, lazy, solve problems in obtuse and circuitous manners, and generally be a pain to wrangle, leading to exhaustion in the best of circumstances. Give every one of those humans a team of obtuse, difficult-to-wrangle AI bots, researchers from Boston Consulting Group discovered, and the problem multiplies.
According to the BCG group's findings [1]published in the Harvard Business Review, AI's promise as an efficiency-driving, work-simplifying agent of liberation for workers hasn't quite panned out.
[2]
Instead, workers are being pushed to create their own teams of AI bots to perform mundane tasks – work which used to be the bread and butter of those human workers. Overeeing those agents is leading to a sort of exhaustion the team has termed "AI brain fry."
[3]
[4]
According to the survey, which included 1,488 full-time US workers, 14 percent (around 208) agreed that they had experienced AI brain fry as defined in the study. While a small percentage, it still suggests that there's yet an additional cognitive drawback to using AI that we haven't really thought about.
It's just like being exhausted from any other intense cognitive task, as the authors define it, saying AI brain fry is "mental fatigue from excessive use or oversight of AI tools beyond one's cognitive capacity." Survey respondents described symptoms of brain fog, difficulty focusing, headaches, and slowed decisionmaking. Some felt as if they had to physically step away from their computer to "reset," they told the authors.
[5]
AI brain fry is distinct from burnout, which the BCG team defined as including "physical and emotional dimensions of distress" that aren't part of this particular problem. This is just plain old exhaustion - probably a lot like what managers of humans experience having to deal with team drama constantly, exacerbated by sitting in one place and staring at a screen for hours on end.
And that fatigue isn't just a feeling - the BCG team said that self-reported error rates among those who felt they were using too much AI were 39 percent higher, meaning businesses are suffering for putting too much on employees' shoulders.
The thing most cited as mentally taxing wasn't using AI, but overseeing AI tools and agents that worked semi-autonomously. Those who reported having to maintain a high degree of AI oversight reported spending 14 percent more mental energy in the workplace, being 12 percent more mentally fatigued, and were 19 percent more likely to say they suffer from information overload in the workplace.
[6]
In terms of job roles, marketers are the most likely to report AI brain fry, followed by HR, ops, engineering, finance, and IT. All those departments, you might note, are particularly prone to AI disruption and the proliferation of agents doing things like writing copy, crunching numbers, and dealing with support tickets.
There's also a clear limit to how big a supervisor can expect an employee's AI toolbox to get: Employees who used a single AI tool and reported adding a second reported a significant increase in productivity. But "as they incorporate a third tool, productivity again increases, but at a lower rate," the team said. "After three tools, though, productivity scores dipped."
BCG expert partner and director Gabriella Kellerman, one of the study's authors, explained that multi-agent systems are increasing in prevalence and that she expects that the number of employees experiencing AI brain fry will increase > unless leaders start to correct the problem now while the heavy-using AI cohort is still small.
"For workers using AI most intensively, this data is an early call for leaders to continue investing in redesigning work," Kellerman told The Register . "Not many workers are using AI this intensively yet, so the number is appropriate for this early stage," Kellerman said in an email, adding that "without a holistic approach to equipping employees with proper training and manager support, AI brain fry has the potential to become a bigger concern."
But sometimes, AI has the opposite effect
There are some uses of AI that weren't as likely to cause brain fry, and could even help relieve symptoms of burnout.
Those able to use AI to offload repetitive, dull, and routine tasks reported feeling 15 percent less burned out, as well as "reporting higher work engagement and motivation scores; more positive emotional associations with AI; and fewer negative emotional associations with AI than others."
Teams who've integrated AI into their processes tend to overall show fewer signs of brain fry, as do those with clear AI training and strategies.

"Our findings suggest that the difference ... is not how much AI an individual uses, but how workers, teams, leaders, and organizations shape its use," BCG said.
"This is a leadership challenge, not just one for individual contributors," Kellerman said. Successful leaders, she added, were those who were available and willing to actively address AI concerns had much more successful, less stressed teams for their efforts. ®

Re: Makes sense
Exactly what I came here to say. It's like trying to manage hard-to-manage, fairly peculiar, reasonably unpredictable interns.
And on the flipside, it helps to have a helper. Not really surprising.

FTFY
"The thing most cited as mentally taxing wasn't using AI, but overseeing AI tools and agents that worked semi-autonomously."
Can't they just use and AI agent to do that?
It's agents all the way down.
Agentrick
The modern developer’s day now begins with a stand-up meeting with their agents. First you ask them what they did yesterday. Then you spawn another agent to verify whether the first agent is telling the truth. Naturally you need a third agent to audit the verification, because trusting the verification agent would be reckless. A fourth agent prepares feedback for the agents about their performance, and a fifth checks that the feedback does not contain hallucinations or hurt the agents’ feelings.
By mid-morning you receive a beautifully formatted report explaining that three agents fixed a bug, two agents reintroduced it, and one agent opened a pull request replacing the database with a JSON file because “it simplifies the architecture.”
The rest of the day is spent supervising a parade of commands the agents would like to execute.
“Delete 14,001 files.”
“Install 37 experimental packages.”
“Rewrite the authentication system in Rust.”
Your job is to stare at the terminal, click “Run,” occasionally click “Deny,” and slowly expand the allow-list so the agents can operate with greater “autonomy.” Around 5 pm. you commit a change that removes the bug the agents introduced in the morning.
Management calls this “10x developer productivity.” In practice it mostly means the human has been promoted to Chief Button-Clicking Officer, responsible for approving the plans of a small committee of very confident robots.
Re: Agentrick
“Rewrite the authentication system in Rust.”
"It's already in Rust"
"Rewrite it in assembler first, then rewrite the assembler version in Rust"
Tradeoff
People will only happily use AI if it's easier to manage their AI than do the task themselves. People also like to use their brains. If you don't even have to think a little bit, you get bored.
Uniquitous use of AI will eventually mean we'll still manage to get stuff done, and either there'll be more output, or it'll be easier to produce it, or both.
Re: Tradeoff
My vote is that there will be a hell of a lot more bloatware. Microsoft & Apple will be happy.
Re: Tradeoff
If you don't even have to think a little bit, you get bored.
That's why it's good to have a side fleet of agents that you can bother when you are bored.
Makes sense
If you're overseeing a fleet of AI agents you obviously didn't have much brainpower to spare to begin with.
Stopped at first mention of BCG.
I still have the scar...
And one on my arm...
If use of an AI
Relieves of drudge work and leaves you to do more high level work that could easily be the reason for exhaustion. It is very difficult to keep working at a high mental level for a full day. If you're used to being able to actually "work" for a full day because half your workday is rote stuff that lets your mind wander while you do it, and suddenly you lose that and you're redlining your brain all day you're gonna get burned out.
At first it'll be fine because of the novelty effect, but once you're "used to" AI and it is no longer novel, you're just burning yourself out.
Makes sense
Anyone whose been in management, has been a project leader or simply been part of a starup when it's under a dozen, knows there's a limit to how many direct reports one can have before things are guaranteed to go south. Before the direct report count reaches that, smart people create some type of oranizational structure so the team can grow without everyone reporting directly to that team leader. Substituting AI for meatbags wouldn't change that, although the maximum workable direct report number with all humans is well above three. But maybe wrangling AI's is more like herding cats or little kids....
