A robot that could fly,work alongside humans,and possess a gentle heart. That vision represented a hopeful destination—a place humanity might reach through scientific progress. Few expect Astro Boy himself to appear.Yet, step by step,our era has been closing the distance toward that imagined future. With the rise of AI,autonomous driving,and automated production systems,technological development has accelerated rapidly. At the same time,new problems have emerged alongside that progress. One of them is energy. AI systems consume electricity to start,to compute,to cool,and to sustain massive data centers. The faster and more capable these systems become,the greater their energy demand grows. This is not merely a technical issue.It is a matter of design assumptions. Astro Boy, in fiction,was powered by an internal nuclear source. While fictional, this detail mattered.The constraint of energy was visible within the story. Modern AI, by contrast,externalizes its energy and cooling requirements.The burden is hidden inside large-scale infrastructure,largely invisible to everyday users. As a result,we do not feel the cost—and therefore, we do not stop. Humanity does not fail to stop because AI is intelligent.It fails because competition-oriented designdoes not allow stopping. If this trajectory continues,the share of global electricity consumed by AI and data centerswill reach a non-trivial level. At current growth rates,estimates suggest roughly 5% of global electricity by around 2035,and approximately 10% by 2041–42,devoted to computation and cooling. This represents a shift in civilizational priorities. So what should we do now? The answer is not simply to build more advanced AI.It is to pause the race—to step away from speed and capability competitions—and to enter an educational phasefocused on how humans and AI should relate to one another. Perhaps the era in which Astro Boy truly appearswill not be defined by technological completion,but by a moment when humans and AIfinally understand each other. That future lies not beyond acceleration,but beyond deliberate pause.
