This conclusion stems the most important factor in assessing the future of technology is not the tool but the ways in which people uses the tools. Tools are "revolutionary" only if they are used, by people, for revolutionary ends. The author uses the word "model" here in the way the physicist Freeman Dyson has used it. Dyson distinguishes between scientific models and scientific theories. Scientists create theories out of logic and mathematics to describe physical systems that are well known, a theory is "supposed to describe the actual universe we live in". Digital work is so ordinary and unremarkable that conferences, collected essays, and professional societies that deal with "Computers and Scholarship" are no longer viewed as relevant. The American Association for History and Computing, which was a cutting-edge professional society two decades ago, has all but disbanded.
