From the human "computers" who tabulated figures in the 1800s to today's agentic coding tools, the work of building and running software has been remade every decade or two. This family spans the people who write and test software, the ones who turn data into decisions, the engineers who keep networks and systems running and secure, and the researchers and quants who push the math forward. Each role carries its own arc; here they sit side by side.
