Machine learning's rise, applications, and challenges

The terms "artificial intelligence" and "machine learning" are often used interchangeably, but there's an important difference between the two. AI is an umbrella term for a range of techniques that allow computers to learn and act like humans. Put another way, AI is the computer being smart. Machine learning, however, accounts for how the computer becomes smart. But there's a reason the two are often conflated: The vast majority of AI today is based on machine learning.
