The God Mode Feeling

By John Koblinsky

For execs and knowledge workers who just vibe coded an app and the sensation that followed.

The euphoria of AI-assisted building — what practitioners call the "god mode feeling" — is not a fluke or a novelty reaction. Neuroscience documents it precisely: dopamine release spikes during creative flow, and unpredictable rewards trigger 3.5 times more dopamine than predictable ones. John Koblinsky at Marsh Island Group examines the mechanism, the proportional crash that follows, and what the neurochemistry actually calls for next.

Why AI-Assisted Building Produces a Stronger Reward Signal Than Most Executive Work

For most executives, building something has always been an act of direction. You define it, resource it, review it, approve it. The making happens elsewhere. AI-assisted development collapses that distance entirely — you are the builder — and the brain, encountering a genuinely novel reward, responds at a scale most professional work never triggers.

The experience has a specific profile. It starts as flow: deep engagement, intrinsic motivation, time distortion. It peaks at the moment the thing works — not "mostly works" but actually runs — and produces something closer to euphoria than satisfaction. Then it returns, briefly, at each successful prompt. And the loop sustains itself in the gaps between successes, through the near-misses that feel more compelling than easy wins.

This is not an accident of personality or a sign of susceptibility. It is the brain's reward architecture operating exactly as designed — encountering a new class of stimulus that triggers mechanisms shaped over millions of years of evolution. Understanding the mechanism doesn't diminish the experience. It explains why the experience matters for how you manage what comes after.

Dopamine Spikes During Creative Flow — and More When Outcomes Exceed Expectations

Researchers at the Karolinska Institute found that "dopamine release in the brain's striatum increases measurably during deep creative engagement, not as a side effect but as the mechanism driving the experience itself," De Manzano and colleagues documented in a 2013 study of dopamine D2 receptors and flow proneness. The brain reinforces the behavior in real time, treating creative engagement as intrinsically rewarding rather than instrumentally useful.

When outcomes exceed prior expectations — what neuroscientists call a positive reward prediction error — the dopamine response is larger still. Your brain is not just marking the moment as successful. It is updating its model of what you are capable of. For an executive who has spent a career directing builders rather than building, that update is a significant recalibration. The electricity is the model revision.

Variable Reward Makes the Loop Neurologically Stickier Than Consistent Success

A 2024 study in Nature Human Behaviour found that unpredictable rewards trigger roughly 3.5 times more dopamine release than predictable ones. Each AI prompt either works or it doesn't, unpredictably and quickly. The near-miss — the prompt that almost produces the right output — is neurologically more compelling than one that always succeeds, because the brain treats near-misses as evidence that success is imminent.

Researchers studying gambling behavior have documented this pattern extensively. The brain's response to a near-miss is almost identical to its response to a win, which is why the loop sustains itself through failure more powerfully than through consistent success. The prompt that fails at 11pm becomes the prompt you have to fix by midnight. This is not a character flaw. It is a slot machine in your editor, and it was designed by evolution. Y Combinator CEO Garry Tan described the experience from the inside: he admitted publicly to staying up until 5am because he was "so addicted" to his AI coding assistant.

Why the Crash After an Intensive AI Build Session Is Proportional to the High

Post-Achievement Depression Is Documented and Predictable

When the session ends — when the thing is built and running and there is nothing left to fix — ordinary work returns. Email. Meetings. Decks. For a day or two, those feel oddly gray. Psychology Today has documented this pattern in creative professionals as post-achievement depression: a sense of purposelessness after completing a long-standing goal, driven by the same dopamine system that fueled the pursuit. Researchers at NeuroLaunch describe the mechanism directly: "once you hit your target, the reward may be short-lived, leaving a temporary vacuum where the drive used to be."

The crash is proportional to the high. It is biological, it is temporary, and it is a signal that something went right — not a signal that something is wrong with the work or with you. Recognizing it as a predictable neurochemical event rather than a mood to override matters for what you decide to do next.

The Re-Entry Trap Starts at the End of the First High

What the crash is not: a reason to immediately open a new project and chase the feeling again. A BCG/HBR study from 2026, led by Bedard and colleagues, documented mental fog, reduced concentration, and increased error rates following intensive AI work sessions — coining the term "brain fry" for the state that follows. The research establishes that cognitive performance in the post-session period is meaningfully degraded, which makes the moment of re-entry into a new AI project the moment of highest risk.

Research documented in the Gerlich (2025) cognitive offloading study of 666 participants found a strong negative correlation between AI usage intensity and critical thinking scores, with the sharpest drops occurring in the period following peak engagement. The transition from healthy flow to compulsive re-entry often starts precisely here — at the end of the first high, when returning to the screen feels like the natural next move and the cognitive capacity to evaluate that decision is at its lowest. John Koblinsky's analysis at Marsh Island Group identifies this transition as one of the under-examined mechanisms within the broader Cognitive Transformation Gap: the point where individual reward-seeking behavior compounds into organizational judgment risk.

What the Neurochemistry Actually Calls For After an AI Build Session

The part that gets lost in conversations about AI productivity is what the time savings actually buys. If a build that would have taken a team three weeks took you three hours, the question is not what to build next. The question is what you have been postponing — the thinking that requires no screen, the conversations that can't be prompted, the unstructured time the brain uses to consolidate what it just learned.

The neurochemical argument is direct. Physical re-engagement — movement, daylight, unhurried time — is what restores baseline dopamine function after a peak. This is the system working as designed. The feeling will return. The rebalance is what makes that return sustainable rather than diminishing.

The practical implication for executives is a scheduling one, not a willpower one. The period immediately following an intensive AI build session is the wrong time to make significant decisions, review important AI outputs, or start the next project. It is the right time to step away. Building that step away into the workflow — not as a reward but as a functional requirement of the neurochemistry — is the difference between a tool that compounds your capability and one that quietly erodes it.

Understanding the god mode feeling is the start. Understanding how that sustained AI immersion erodes judgment if the recovery loop is skipped is what determines whether the capability compounds or the tool takes over.

FAQ

Frequently Asked Questions

What is the "god mode feeling" in AI vibe coding? expand_more

The god mode feeling describes the euphoria that follows successfully building something with AI assistance — distinct from ordinary professional satisfaction. Researchers at the Karolinska Institute documented that dopamine release in the brain's striatum spikes during deep creative engagement not as a side effect but as the mechanism driving the experience itself. For executives accustomed to directing builders rather than building, the brain's response to the novel reward is outsize.

Why does AI-assisted development trigger such a strong dopamine response? expand_more

Two mechanisms compound. First, dopamine spikes during creative flow states, reinforcing the behavior in real time. Second, when outcomes exceed prior expectations — a positive reward prediction error — the response is larger still. The brain is not just marking the success; it is revising its model of what the person is capable of. For executives who have not previously experienced themselves as builders, that revision produces something closer to electricity than satisfaction.

How does variable reward in AI vibe coding create an addictive loop? expand_more

A 2024 study in Nature Human Behaviour found that unpredictable rewards trigger roughly 3.5 times more dopamine release than predictable ones. Each AI prompt either works or doesn't, unpredictably. The near-miss — the prompt that almost produces the right output — is neurologically more compelling than consistent success because the brain treats near-misses as evidence that success is imminent. The prompt that fails at 11pm becomes the prompt you feel compelled to fix by midnight.

What is "brain fry" in AI-intensive work? expand_more

"Brain fry" is the term coined in a 2026 BCG/HBR study by Bedard and colleagues to describe the state following intensive AI work sessions: mental fog, reduced concentration, and increased error rates that persist into the hours and day after peak engagement. The study documents that cognitive performance in the post-session period is meaningfully degraded — precisely when starting the next project feels most compelling.

Why do executives feel a gray period after a major AI build session? expand_more

Psychology Today has documented this pattern in creative professionals as post-achievement depression: a sense of purposelessness after completing a significant goal, driven by the same dopamine system that fueled the pursuit. The crash is proportional to the high and is biological, not dispositional. Researchers at NeuroLaunch describe the mechanism as a temporary vacuum where the drive used to be — predictable, finite, and a signal that the engagement was genuine.

Does the Gerlich cognitive offloading study apply to executive AI use? expand_more

The Gerlich (2025) study of 666 participants found a strong negative correlation between AI usage intensity and critical thinking scores, with the sharpest drops in the period following peak engagement. The pattern is directly relevant to executives: the moment of post-session re-entry is when cognitive capacity for evaluating the next project is lowest. This window requires the most structural protection, not the least.

What should knowledge workers do immediately after an intensive AI build session? expand_more

Step away — not as a reward but as a functional requirement of the neurochemistry. Physical re-engagement — movement, daylight, unhurried time — is what restores baseline dopamine function after a peak. Building that step away into the workflow as a structured requirement, rather than a willpower decision made at the end of a depleted session, is the difference between a tool that compounds capability and one that quietly erodes it.

Is the euphoria from AI vibe coding a sign of problematic dependency? expand_more

Not inherently — but the transition from healthy engagement to compulsive re-entry is a real risk that starts at a specific and predictable point: the end of the first high, when cognitive capacity is degraded and returning to the screen feels natural. Gerlich (2025) shows the sharpest critical thinking drops occur in that post-peak window. Recognizing the pattern structurally — and scheduling recovery accordingly — is what keeps the reward loop productive rather than compulsive.
