Artificial intelligence can mimic human intellect and behavior through tasks like solving mathematical problems, common sense reasoning, and expert knowledge in fields like law and medicine. It also aims to achieve goals and be measured by performance like humans. The document discusses making computers think through modeling the human brain with a network of neurons transmitting signals, and how this could lead to an artificial brain that acts as a personal assistant. Both advantages like decision making without humans and disadvantages like dependency and personal information hacking are discussed. The project aims to first create an advanced conversational bot and then upgrade it to an artificial brain to provide personal assistance.
