While Asset bubble burst was one of the top- ranked long-term risks during and in the immediate aftermath of the financial crisis, its ranking subsequently fell off sharply as the global economy regained a stable footing in subsequent years. Technological acceleration is the structural force to watch Perceptions of long-term technological risks have been among the most volatile of all the risks considered in the last 20 years of the Global Risks Report. While this can be explained by the current set of technology risks being relatively new to the report, it nonetheless is a warning sign that technological risks might be the area to watch the most for unexpected future risk developments. The impacts of technological acceleration are difficult to assess. Even going back to the first edition of the Global Risks Report in 2006, it was noted that risks associated with new technologies were among those whose outcomes were very unclear. Over the course of the 20 editions of the Global Risks Report, the category of technology has itself changed frequently, with risks in 2006 related to the Convergence of technologies, Nanotechnology, Electromagnetic fields and Pervasive computing. Such threats have evolved markedly and today the category includes Misinformation and disinformation, Censorship and surveillance, Adverse outcomes of frontier technologies, Adverse outcomes of AI technologies, and Cyber espionage and warfare. Undoubtedly, this categorization will be subject to further significant realignment in the coming years given the pace and range of different possible directions of technological change. 44403025201510510-year risk rank 351 Year2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2022 2023 2025 2024 2017 2018 2019 2020 2021 Debt and Asset bubble burst: Evolution in ranking, 2009-2025 FIGURE 2.20 Source World Economic Forum Global Risks Report, 2009-2025.Asset bubble burst Debt (public, corporate, household) No data Global Risks Report 2025 69
