This global challenge of rapidly changing skill requirements due to task automation overwhelms workers. The digital skill gap widens further as technological and social transformation outpaces national education systems and precise skill requirements for mastering emerging technologies, such as Artificial Intelligence, remain opaque. Online labour platforms could help us to understand this grand challenge of reskilling en masse. Online labour platforms build a globally integrated market that mediates between millions of buyers and sellers of remotely deliverable cognitive work. This commentary argues that, over the last decade, online labour platforms have become the \u2018laboratories\u2019 of skill rebundling; the combination of skills from different occupational domains. Online labour platform data allows us to establish a new taxonomy on the individual complementarity of skills. For policy makers, education providers and recruiters, a continuous analysis of complementary reskilling trajectories enables automated, individual and far-sighted suggestions on the value of learning a new skill in a future of technological disruption.<\/jats:p>","DOI":"10.1177\/20539517211003120","type":"journal-article","created":{"date-parts":[[2021,4,15]],"date-time":"2021-04-15T01:48:25Z","timestamp":1618451305000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":19,"title":["One size does not fit all: Constructing complementary digital reskilling strategies using online labour market data"],"prefix":"10.1177","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0713-6010","authenticated-orcid":false,"given":"Fabian","family":"Stephany","sequence":"first","affiliation":[{"name":"Oxford Internet Institute, University of Oxford, Oxford, UK"},{"name":"Humboldt Institute for Internet and Society, Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,4,14]]},"reference":[{"key":"bibr1-20539517211003120","doi-asserted-by":"crossref","unstructured":"Acemoglu D, Autor D.
