The “short arm” of predictive knowledge highlights the limitations of forecasting future cyber threats with certainty, given the rapidly evolving nature of technology and cyber tactics. In developing cyber-policy and infrastructure, we should adopt a flexible, adaptive approach that emphasizes resilience, rapid response, and continuous learning. Rather than relying solely on long-term predictions, policies should prioritize robust cybersecurity frameworks that can quickly adapt to new threats, support real-time threat intelligence sharing, and encourage innovation in defensive technologies. By focusing on agility, collaboration, and preparedness, we can better navigate the uncertainties inherent in cybersecurity.
