Final answer:
Microsoft's Cortana and Apple's Siri are examples of weak artificial intelligence, which is designed to perform specific tasks such as voice recognition in smartphones. Strong AI, which performs multiple cognitive tasks like humans, is a matter of philosophical debate concerning whether machines can possess consciousness.
Step-by-step explanation:
Microsoft's Cortana and Apple's Siri are utilities that exemplify the use of artificial intelligence (AI) in everyday technology. Incorporating AI into devices like smartphones allows for features such as voice recognition, enabling these devices to understand and respond to human voices, a capability that's been integrated into cell phones since around 2015.
AI can be categorized into two types, strong AI and weak AI. Strong AI refers to systems capable of performing multiple cognitive tasks similar to a human but much faster. In contrast, weak AI is designed to carry out one specific task effectively, which is the case with Siri and social media bots. However, despite ongoing innovations, philosophers like John Searle argue that no technology today exhibits true strong AI, as it lacks intentionality and consciousness.
