Amplification of Advantage
The specific mechanism by which AI tools widen existing gaps: equal tool access applied to unequal foundations produces larger absolute differences in output, because amplification multiplies the foundation. The Matthew Effect rendered in AI terms.
Amplification of advantage is the specific predictive claim
Toyama's framework makes about AI in a world of unequal foundations. When the same tool is available to users with radically different levels of educational preparation, institutional support, market access, and cultural capital, the tool's amplification factor operates on those differences. A twenty-fold multiplier on a deep foundation produces much more output than the same multiplier on a shallow foundation — not because the tool is unfair but because multiplication of unequal quantities yields unequal results. The prediction is not that AI will fail to benefit those with weaker foundations; it is that AI will benefit them less than it benefits those with stronger foundations, widening the absolute gap even as both groups experience genuine gains.

The dynamic is most visible in software development, where the pattern can be measured directly. Before AI coding assistants, the productivity gap between senior and junior
