How has the portrayal of artificial intelligence in movies evolved over the decades?

The depiction of artificial intelligence in films has significantly shifted from the 1950s to today, reflecting changing societal attitudes and technological advancements. Initially, movies often portrayed AI as menacing entities capable of human destruction, like in "2001: A Space Odyssey" or "The Terminator." Over the years, films such as "Her" and "Ex Machina" introduced more nuanced characters that explore themes of companionship and ethical dilemmas. This evolution raises fascinating questions about how cinema mirrors real-world tech developments and influences public perception of AI.
