While most of the buzz around artificial intelligence (AI) may seem new, the concept has been around for more than 60 years. American computer scientist John McCarthy, known as the "Father of AI," coined the term "artificial intelligence" in the 1950s, leading researchers across the United States to dig into the computer learning for processing equations and theorems. In the 1960s, computer scientists began creating machines similar to robots, and the first humanoid robot was built in Japan in 1972. Unfortunately, it was difficult for scientists to go any further due to the lack of advancement in data technology, and the period between the mid 1970s and early 1990s saw a drop-off in serious development. But in the 1990s, computers became more advanced.
