General-Purpose Technology

# General-Purpose Technology A **general-purpose technology** is a capability whose value expands through use across many sectors, improves over time and generates complementary innovations and organizational changes. Steam power, electrification, semiconductors and computing are standard historical examples. ## Reorganization lag Paul David's work on the electric dynamo showed that a technology's invention can precede its largest productivity effects by decades because factories, workflows and institutions must be rebuilt around it. Erik Brynjolfsson, Daniel Rock and Chad Syverson apply this productivity-lag framework to artificial intelligence. ## AI as a deeper case [[articles/We Cannot Un-Strike the Match|We Cannot Un-Strike the Match]] argues that AI belongs in this category while also pressing beyond it: machine intelligence can participate in designing the next amplifications. The historical analogy is therefore necessary for understanding diffusion and incomplete for understanding recursive cognitive production. ## See Also [[wiki/Artificial Intelligence|Artificial Intelligence]], [[wiki/Automation|Automation]], [[wiki/Economic Transition|Economic Transition]], [[wiki/Technological Evolution|Technological Evolution]] ## Simple Reminders, Quotations, and Thoughts  > “Comparisons between artificial intelligence and earlier general-purpose technologies are simultaneously necessary and insufficient: they teach us how civilization responds to radical transformation while reminding us that we have never previously transformed the substrate of problem-solving itself at this velocity.” > **— Bryant McGill**, *We Cannot Un-Strike the Match.
