“Critically Extant” is a project that explores just how little we know about the natural world by testing the limits of the data openly available to us. To achieve this, AI algorithms were trained on millions of open source images of nature and some ten thousand species. The resulting models were then used to generate visual representations of species that are critically endangered, yet have little or no online presence. A project exploring the limits of available data as a means of engaging with critically endangered species. By only using open, publicly available data, representations are generated that reflect upon how little (or much) they are present in our everyday, digital lives.
