It wasn't that long ago that artificial intelligence (AI) was a futuristic concept. Now, computer systems can complete tasks that historically required human intelligence. Smart home systems like Amazon Echo and intelligent personal assistants like Siri can understand your commands and complete tasks for you. You don't even need a partner to play games anymore-computer systems, like DeepMind's AlphaMind Zero for the game Go, can be your counterpart in multi-player games.
