There have been attempts at creating artificial intelligence for several decades. It is an emerging field that is currently in its formative stages. Despite the diversity of AI systems, several researchers and scientists predict that AI will one day surpass human intellect. This could occur for a number of different causes. Secondly, AI is constantly improving and is now reaching human levels of sophistication. For another, computers and people are fundamentally different. At last, computers can learn from their mistakes and act autonomously without being programmed. As AI can only interpret the data that is already accessible and cannot develop any new data, it cannot replace human intelligence, but with enough training on large amounts of data, it could someday become better at performing things than humans. As humans are the primary source of data, artificial intelligence will never be able to compete with humans.
