The focus of the HiPEAC Vision 2023 is that we are in races, both against time and with the rest of the world. Technology never stands still. The last few years have once again seen rapid, profound changes across the world, both from the technological point of view – with impressive advances in artificial intelligence – and from the geopolitical point of view, where technology is increasingly seen as a strategic asset. Different world regions are competing for leadership in several areas. Competition between the United States (US) and China in the technology and artificial intelligence (AI) domains is particularly fierce, and it is becoming more intense. This creates a threat to Europe, but at the same time an opportunity. The recent change of ownership and leadership at Twitter is also a wake-up call for Europe. Many of the essential services the European society depends on run on platforms that are not controlled by Europe. This creates vulnerability in the event of conflict, comparable to European dependency on Russian energy. These are just the evolutions of the last year. Change is taking place so fast that it is also having an impact on the HiPEAC Vision: updating it every two years is no longer sufficient to keep up with the speed of the evolution of computing systems. Therefore, from now on, there will be a HiPEAC Vision every year. The speed of the evolution has also inspired the editorial board to present the challenges of our community as six leadership races: for the “next web”, for AI, for innovative hardware solutions, for cybersecurity, for digital sovereignty, and for sustainability solutions. Structurally, the HiPEAC Vision 2023 has two parts: - A set of recommendations for the HiPEAC community at large. - A set of articles written by experts and grouped into six chapters each describing one “global leadership race”. We encourage you to read the complete document, but to clearly understand the recommendations, the reader should read at least the following section “The drivers of the HiPEAC Vision 2023” and the “Key recommendations of the HiPEAC Vision 2023”. The HiPEAC Vision will be available on the HiPEAC website, with easy access to each article, and to the consolidated version. The consolidated version of the Vision will also be printed and distributed, as with previous editions
