Key Takeaway
- AI technology is 100 times faster, but our brains are biologically identical to those of our Ice Age ancestors from tens of thousands of years ago.
- The task of reviewing the massive output generated by AI imposes extreme cognitive overload, much like constantly monitoring and taking responsibility for the trajectory of a ‘self-driving car’.
- We must stop syncing ourselves to the speed of machines and protect our core decision-making power through intentional ‘mental pauses (analog organization)’.
Conversing with AI Using a Stone Age Brain#
It’s no exaggeration to say that human history is the history of tool development. However, there is one shocking scientific fact. As of 2026, while we process complex tasks conversing with top-tier AIs like ‘GPT, Claude, and Gemini’, our brains are biologically identical to those of our ancestors who lived alongside mammoths during the Ice Age over 10,000 years ago.
From an evolutionary biology perspective, it is a well-established theory that the structure and information processing capacity of the human brain have hardly changed over the past tens of thousands of years. In other words, equipped with outdated, one-dimensional hardware originally designed to react to physical threats like a rustle in the bushes, we are facing the flood of information in the AI era—trillions of data points per second—head-on, completely naked.
1. Explosive Efficiency, Screaming Brain#
With the advent of AI, task efficiency has exploded to an incomparable degree. Planning documents or data analyses that used to take days can now be organized into text and tables in just a few minutes with a few lines of a prompt. However, the human brain operating these incredibly powerful tools is suffering from severe overload.
A prime example is the fatigue experienced when using ‘LLM services’. To a single line of a light question we throw, AI churns out an answer equivalent to dozens of pages of a thesis or report in just 1 second. The moment we read that overwhelming wave of text to grasp the core points, our brain’s cognitive threshold is pushed to its absolute limit every single time.
The speed of getting results has become 100 times faster, but the process of the brain understanding and absorbing them has become 100 times more painful. Doesn’t it feel like being forced to sit through an endless stream of highly advanced ‘graduate school lectures’ day after day?
2. The Paradox of Self-Driving Cars: The Fatigue of the Final Decision Maker#
This cruel situation aligns exactly with the metaphor of the ‘self-driving car’. Due to the development of autonomous driving technology, a car’s driving performance has improved beyond comparison to the past. The car finds the optimal route, changes lanes, and avoids obstacles on its own. However, the ‘core decision-making process’—setting the destination (where to go) and deciding whether to hand over the steering wheel while monitoring, “Is this machine’s judgment safe enough to risk my life?"—still belongs to us humans.
The ‘human’, as the final decision-maker, must constantly monitor and confirm whether the route set by the autonomous driving feature is what I originally intended, and whether the machine’s analysis in unexpected situations is truly correct. Surprisingly, this process of ‘surveillance and final approval’ imposes a much more intricate and insidious overload on the brain than when I hold the steering wheel and press the accelerator myself.
AI has taken over the physical labor of heavy lifting, but the paradoxical situation is that our brains are now fully burdened with the most exhausting ‘mental labor’ of picking the right answer at hundreds of crossroads derived from it.
3. How to Survive: The Speed of the Brain, Not the Machine#
We must not synchronize ourselves to the frantic speed of machines. Abandon the illusion that just because you use a tool that is 100 times faster, your brain will also become 100 times faster.
- Take Mental Pauses: When AI pours out massive blocks of text, do not immediately fire off the next follow-up question without catching your breath. You must allow your brain the ‘physical time’ to digest that vast amount of information and connect it with existing knowledge.
- Escape the Subscription Prison: Another way to reduce brain overload is to take full control of your tools. Instead of paying monthly for services, consider building a local AI environment that runs directly on your hardware.
- Protect the Authority of Final Decisions: No matter how polished and perfect the answer AI provides may seem, never lose the power of critical thinking to ask if it aligns with the destination you originally set. The more uncritically you rely on the machine’s judgment, the smaller your control becomes, and an unidentifiable anxiety will only grow.
- Analog Organization: If you feel your mental energy draining in the overwhelming ocean of information, occasionally take your eyes off the monitor and pick up a pen and paper. The most comfortable and powerful information organization method for our ‘Stone Age brains’ is not smooth typing, but the time of analog contemplation, clumsily drawing lines by hand.
Arthur G.’s Perspective: Becoming the Master of Tools Again#
The explosion of productivity seems like a blessing on the surface, but if we do not become its masters and controllers, we will simply drown in the daily flood of information, experiencing the helplessness of a brain like a student bogged down by graduate school assignments.
Technology is running madly toward a future 10,000 years away, but the biological brain that makes up who we are still yearns for the peaceful sounds of the forest and deep contemplation, doing things one at a time. It is time to listen to the silent screams of the brain hidden behind the explosive convenience that AI provides.
A far more important and urgent survival task than wielding tools incredibly well is keeping our ‘Stone Age brain’, which operates those tools, healthy and unexhausted.
