Yet according to the same report, after adopting AI, employees spent more time on email, messaging and administrative work—not less. AI removed some effort, but it also introduced another layer of decisions: what to automate, what to review, when to trust the output and how to coordinate work done not only by humans but also by agents.
For years, much of management revolved around coordinating work: assigning tasks, reviewing progress and making sure information reached the right people. AI is now taking over more of that coordination. A Harvard Business School study of developers using GitHub Copilot,
reported in Harvard Business Review, found that once teams adopted AI, they spent more time on their core work and less on project management and coordination.
Stanford's research on changing workplace skills explores how the key human skills are shifting: As AI takes over more information processing, the value of organizing work, communicating clearly and helping people collaborate continues to rise.
This has changed what a leader is for. Teams depend far less on leaders for information and coordination. Now the most important leadership job is to reduce the complexity of the modern workplace.
The catch is that complexity tends to accumulate. When we want to improve something, our instinct is to add. We add a new tool or a new team member to help with the workload or a new project. But with every addition, the level of complexity only increases.
Research published in Nature suggests that this isn't just how organizations behave—it's also how people think. Across eight experiments involving more than 1,500 participants, researchers found that people consistently looked for ways to add rather than remove, even when subtraction produced an equally good solution. The busier people felt, the less likely they were to consider simplifying at all.
Adding is easier to think through, and there is a cultural pull behind it, since we tend to read "more" as ambition and measure ourselves by what we have built rather than by what we have set aside. Reducing complexity means working against that instinct and treating subtraction as a deliberate practice. It means you need to decide what's no longer relevant to make priorities easier to see and give people the space to focus on work that actually matters.
