Plant's work is primarily concerned with the impacts of technological developments, including the side effects of its progress.

[5][6] Her original research was related to the Situationist International before turning to the social and political potential of cyber-technology.

She published a cultural history of drug use and control, and a report on the social effects of mobile phones, as well as articles in publications as varied as the Financial Times, Wired, Blueprint, and Dazed and Confused.

In 2003 Plant wrote a chapter in The Information Society Reader,[9] titled "The Future Looms: Weaving Women and Cybernetics."

Here Plant writes about the entwined history of women and the field of cybernetics through the figure of Ada Lovelace.
