Summary

In this Big Think interview, David Alan Grier, author of ‘When Computers Were Human’, argues that the computing revolution began in 1776, not with electronic computers, but with the systematization of calculation during the Industrial Revolution. He traces the origins of computing to the need to process vast amounts of astronomical data, such as predicting the return of Halley’s Comet and producing navigational tables for the Nautical Almanac. This work was performed by ‘human computers’ who used division of labor and error-checking techniques to ensure accuracy. Grier highlights the role of Charles Babbage, who, inspired by the need for reliable tables, conceived of the Difference Engine, a mechanical calculator that could automate the process of polynomial approximation. Although Babbage’s machine was never completed, his ideas about systematizing calculation laid the groundwork for modern computing. The talk also explores the influence of clockwork technology, which provided the precision and control mechanisms that later became essential in early computers. Grier emphasizes that the history of computing is not just about hardware and software, but about the industrial processes of standardization, quality control, and cost reduction that continue to shape the field today.

Critical Evaluation

Value of the Information & Strength of the Argument

The video provides a valuable historical perspective on the origins of computing, challenging the common narrative that it began with electronics. Grier’s argument is well-structured, using concrete examples like the Nautical Almanac and the work of human computers to illustrate the principles of division of labor and error correction. He effectively connects these early practices to modern computing concepts, such as algorithms and systematization. The argumentation is persuasive, though it relies on anecdotal evidence and historical narrative rather than rigorous data analysis. The speaker’s expertise adds credibility, but the lack of formal citations limits the scientific rigor.

Scientific Rigor, Source Quality, Title Accuracy

The talk is based on Grier’s book ‘When Computers Were Human’, which is a well-regarded historical account. However, the video itself does not cite specific sources, and the narrative is presented as a personal interpretation. The title accurately reflects the content, which is a historical argument about the origins of computing. The content is generally accurate, but some simplifications are made for a general audience, such as the claim that the computing revolution ‘secretly began in 1776’, which is a rhetorical device rather than a precise historical fact. The speaker’s credentials as an IEEE Fellow and author on the topic lend authority, but the lack of direct citations in the video reduces its scientific rigor.

Title / Content Match

The title accurately reflects the content, which argues that the computing revolution began in 1776 with the systematization of calculation, not with electronic computers.

Quality & Reliability

8/10

The speaker is a recognized expert (IEEE Fellow, author of 'When Computers Were Human'), and the content is historically grounded, referencing key figures and events. However, the talk is an opinion-based narrative without formal citations or peer-reviewed sources, and some claims are simplified for a general audience.

Key Moments

Cited Sources

  • Big Think Membership — Promotional link in the video description, not a source for the content.

Concurring Sources

  • When Computers Were Human — The book by the speaker, which provides a detailed account of human computers and aligns with the video's narrative.

Dissenting Sources

  • The Myth of the 'First Computer' — Some historians argue that the term 'computer' should be reserved for electronic devices, and that earlier mechanical calculators are not true computers. This perspective contrasts with Grier's broad definition.

Contribution & Novelties

The video offers a fresh perspective by framing the history of computing within the Industrial Revolution, emphasizing the role of human computers and systematization rather than focusing solely on electronic inventions. It highlights the importance of error-checking and division of labor as foundational principles. This historical context is often overlooked in popular narratives.

Pour aller plus loin :

  • When Computers Were Human — The book by David Alan Grier that provides a detailed history of human computers.
  • Difference Engine — Charles Babbage’s mechanical calculator, a key example of early computing hardware.
  • Nautical Almanac — The publication that required extensive human computation for navigation.
  • Division of labour — The economic concept that underpins the systematization of work, as discussed by Adam Smith.
