Just as artificial intelligence aims to replicate human intelligence, artificial stupidity can arise from the replication of human errors or limitations in the AI systems. This can manifest in various ways, such as incorrect decision-making, flawed reasoning, or inability to learn from mistakes. Therefore, the presence of artificial intelligence does not guarantee the absence of artificial stupidity. **
