                ### Self-Healing AI Systems
                Systems capable of detecting, isolating, and recovering from adversarial perturbations
                without human intervention. Key capabilities include:
                - Real-time anomaly detection
                - Automated threshold adjustment
                - Rollback to known-good states
                
                ### Self-Generating Models
                AI systems that can generate novel attack vectors and defense mechanisms autonomously.
                These models create new strategies based on:
                - Pattern recognition from historical attacks
                - Evolutionary algorithms
                - Reinforcement learning from security outcomes
                
                ### Regenerative Security
                Security architectures that continuously rebuild and strengthen defenses based on:
                - Real-time threat intelligence
                - Automated patch deployment
                - Self-modifying rule sets
                
                ### Infinite-Step Attacks
                Prolonged adversarial campaigns that:
                - Adapt to defensive measures
                - Learn from detection patterns
