Artificial intelligence (AI) aims to make machines intelligent like humans by studying patterns in the human brain. There are four main types of AI from purely reactive machines to self-aware systems. In contrast, human intelligence involves complex cognitive processes and is influenced by subjective factors. While AI can process information faster and more accurately, human intelligence is better at adapting, multitasking, social interaction, and self-awareness. Theories also describe human intelligence as involving multiple abilities and AI is focused on optimization versus human intelligence's role in innovation.
