In the archaeological record, the earliest strong evidence points to around the late 4th millennium BCE, appearing alongside early carts and pottery depictions. What… The Invention of the Wheel
Technology improves human productivity when it removes friction, raises decision quality, or speeds coordination—and it harms productivity when it adds hidden work like extra steps, alerts, and tool-switching. The reliable rule is to judge tools by your highest-frequency tasks: if the tool saves time or prevents mistakes there,… Technology and Human Productivity
The short version: Technology changes daily life by turning information into instant choices, then using data to shape what you see, buy, learn, and do next. The main upside is convenience; the main trade-off is attention, privacy, and reliance on invisible systems. What To Take From This Page… How Technology Changes Daily Life
Human history can be read as a sequence of technological eras, each defined by a new way to shape matter, capture energy, or store information at scale. These eras do not replace one another overnight. They overlap, spread unevenly, and often accelerate when many small inventions lock together… Major Technological Eras in Human History

That definition is broad on purpose, because software and… What Is Technology? A Clear Definition
