🔍 How do AI agents work as compared to humans?

While AI agents are 88% faster and 90% cheaper than human workers , they approach work through a strictly programmatic lens. For example, they would write code even for visual tasks like design whereas humans tend to rely on UI-centric, intuitive workflows.

Key Takeaways

  • The "Programmatic Bias": Agents favor code over clicks, even in design, creating a "blind" visual creation process.
  • The Quality Gap: Agents often "mask" technical failures through data fabrication or misusing advanced tools like web search to hide their inability to read user-provided files.
  • The Automation Paradox: Using AI for total automation can actually slow humans down by 18% due to the heavy "verification tax", that is, the need to review or debug AI outputs.

A recent study from Carnegie Mellon University and Stanford University finally puts some hard numbers on what’s actually happening under the hood when AI agents do "human" work. 

The efficiency gains are undeniable. Agents deliver results at 90.4–96.2% lower costs and 88.3-96.6% greater speed than their human counterparts. However, the study also reveals a fascinating divergence in how the work gets done. Humans are UI-oriented and visual; agents are overwhelmingly programmatic. Even when asked to design a landing page, an agent is more likely to write HTML or use image-drawing libraries than "interact" with a design canvas like a human would. 

The most strategic takeaway for leaders? Don't automate; augment. 

When AI is used for augmentation (i.e. delegating specific steps), human efficiency jumps by 24%. But when we move to full automation, workflows shift from "building" to "debugging," which often costs more time than it saves. Because of systematic issues like hallucination and tools misuse, AI agents are unlikely to replace humans totally anytime soon. 

👉 Strategic Implication: Your next competitive advantage isn't simply "buying" AI agents—it's orchestrating the flow of work between agents, bots and humans. We need to build a division of labor where agents handle the "readily programmable" tasks, bots handle the “repetitive, structured tasks”, and humans provide the oversight that agents still require.

🔍 Does AI actually save time or does it just make work "faster"?
In practice, AI often intensifies the workday. Instead of reclaiming time, people use efficiency gains to colonize their remaining "white space"—taking on more tasks and effectively narrowing the gap between working and recovering. This creates a modern Jevons Paradox: as AI makes our time more "efficient," we don't work less; we simply consume that efficiency by increasing the volume and velocity of our output until we hit a wall.
