What this part means

Capital delta attached to a quantity marks a difference between two values of that quantity; the article’s sign convention determines the order.

The passage around this formula

What is genuinely different is the exposure profile, not the mechanism. Routine-biased technical change hollowed the middle because rule-following tasks were the cheapest to codify [ 13 , 15 ] . Language models are strongest where output is text-shaped, tacitly specified and cheaply verified — which places a substantial share of professional and clerical work inside the exposure set for the first time. That changes who is exposed. It does not change the task-based arithmetic, and it does not by itself determine the sign of Δ\Delta ln⁡\ln L .
