Introduction to Artificial Intelligence

The four main types of artificial intelligence, categorized by their functionality and capability, are reactive machines, limited memory, theory of mind, and self-aware AI. The first two types exist today (Narrow AI), while the latter two are theoretical, future concepts.

AI will not replace jobs requiring high emotional intelligence, complex creativity, strategic decision-making, or specialized physical skills in unpredictable environments. Key AI-resistant fields include healthcare practitioners (nurses, therapists), skilled trades (electricians, plumbers), strategic leaders, educators, and creative artists. These roles depend on human empathy, nuance, and physical adaptability.

As of early 2026, ChatGPT (OpenAI) is the most used AI tool globally, boasting 900 million users and 2.7x more traffic than the next competitor, making it the leader in text generation and general AI usage. Other top, highly used AI tools include Gemini (Google), Claude (Anthropic), and Microsoft Copilot, which is deeply integrated into Microsoft 365 apps.

Ultimately, AI is not a replacement for human intelligence; it's a tool that can help us achieve our goals, but we need to ensure that we use it responsibly and ethically. Furthermore, humans bring a wide range of experiences, creativity, and intuition to the decision-making process that AI cannot replicate.

Human-Like Experiences & Emotions Experience emotions – AI can simulate emotions but does not actually feel them. Have self-awareness – AI doesn't have subjective experiences or a sense of "self."
