In the months following December 2025, a pattern emerged among experienced software engineers: some, often the most senior and accomplished, began reducing their cost of living. They moved out of expensive cities. They paid off debts. They downsized. They talked about homesteading, about self-sufficiency, about building a life that could sustain itself on a fraction of their current income. In the language of the moment, they were running for the woods. Other engineers, equally senior and equally aware of what was happening, did the opposite — leaning into AI tools with an intensity that bordered on compulsion, doubling down on the fight. Both responses are rational. Becker's framework does not predict that all agents will respond the same way to a shift in returns. It predicts all agents will respond in ways consistent with their individual constraints, risk preferences, and assessments of the probability distribution.
Consider the runner. She is fifty-two years old, with a mortgage, two children approaching college age, and twenty-five years of accumulated expertise in backend systems architecture. Her human capital is overwhelmingly specific — tied to particular technologies and a market that valued the kind of deep, narrow expertise she spent her career developing. The AI transition has reduced the expected return on that capital. She performs Becker's calculation: the present value of remaining career earnings under the old regime versus the new one. The difference is stark. Her rational response is risk reduction. Lower the fixed costs. Eliminate the mortgage. Move to a place where the cost of living is a fraction of what it was. Build a life sustainable on a lower income, because the income trajectory has changed. This is not panic. It is portfolio rebalancing — the same logic that drives an investor to shift from equities to bonds when volatility increases.
Now consider the fighter. He is thirty-eight, unencumbered by a mortgage, with a general capital portfolio that includes not just technical skills but product judgment, cross-domain integration, and the capacity to communicate complex ideas to non-technical audiences. His human capital is disproportionately general — the kind that appreciates when specific capital around it depreciates. The AI transition has not reduced his expected return. It has increased it, because the tools have removed the friction that previously consumed eighty percent of his working hours.
His rational response is investment amplification. Use the tools. Build faster. Take on more. When every hour of work produces what ten hours produced before, the implicit price of not working — of resting, reflecting, reading, doing nothing — has risen by a factor of ten. The productive compulsion the Berkeley researchers documented is not a pathology of will. It is a rational response to a price change.
Yet the rationality of the response does not validate the outcome. Tens of thousands of senior engineers running for the woods simultaneously produces a mass withdrawal of experienced judgment from the technology sector — precisely when experienced judgment is most needed. Tens of thousands of knowledge workers fighting around the clock simultaneously produces a workforce running at unsustainable intensity, eroding the cognitive and relational capital that sustains judgment over time. The individual optimization produces a systemic failure.
The flight-fight pattern was documented by Segal in The Orange Pill through direct observation of his own professional network and the broader software engineering community in 2025–2026. Becker's framework provides the economic substrate: the amygdala fires, but the direction of the response is shaped by the agent's capital portfolio, risk tolerance, and assessment of future returns. Both the runner and the fighter are mammals calculating under stress, and both are correct about the facts.
Both responses are rational. The difference between runner and fighter is not a difference in rationality — it is a difference in the parameters of the optimization (capital portfolio, risk tolerance, time horizon).
Portfolio rebalancing, not surrender. The flight to the woods is what it looks like when a rational agent adjusts fixed costs downward in response to a shift in the expected return trajectory.
Intensification, not pathology. The fight response is what it looks like when the shadow price of leisure has risen dramatically, making continued intense work the rational allocation.
Neither response alone is sufficient. Collectively, the rational individual responses produce systemic outcomes — talent withdrawal and sustained overwork — that no participant intended and that no market mechanism will correct without institutional intervention.
