Abstract: This paper explores the profound impact of Artificial Intelligence (AI) on Human Intelligence (HI), examining both the enhancements and challenges AI introduces. AI, defined as the capability of machines to perform tasks requiring humanlike intelligence, has evolved significantly, influencing various domains such as education, healthcare, and the workforce. AI enhances human cognitive processes by assisting in decision-making, problem-solving, and creativity, thereby augmenting HI. In education, AI-driven tools offer personalized learning experiences, while in healthcare; AI improves diagnostics and patient care. However, the integration of AI raises ethical concerns, including privacy, data security, and algorithmic bias. The potential for AI to surpass human intelligence, known as the singularity, poses existential questions about human autonomy. This paper underscores the importance of responsible AI development, emphasizing the need for ethical frameworks to balance technological advancements with human values. As AI continues to advance, fostering effective human-AI collaboration and preparing society for an AI-enhanced future are crucial for maximizing the benefits and minimizing the risks associated with AI's influence on HI.
