Forget what you may have heard. Machine learning isn't some new concept or study in its infancy.

If we're being technical, machine learning has actually been around since the 1950s, when Arthur Samuel coined the term at IBM. Early statistical models in those days paved the way for today's modern artificial intelligence.

On the contrary, while today's machine learning is miles ahead of what it used to be, there's always room for improvement.

With advancements in algorithms, statistical modeling, and computing, machine learning will only get more efficient. And while it's not always easy to predict what this efficiency will look like, some experts have an idea.

So, we asked 5 people with in-depth knowledge of machine learning for their opinions on its future. Let's see what they had to say.
