Some people scroll through their Twitter feeds or check up on emails when they have a spare moment. But American investor, Shark Tank judge, and owner of the Dallas Mavericks, Mark Cuban does something a little different.

He learns about artificial intelligence.

On one podcast episode of Recode Media with Peter Kafka, Cuban explains, "If you go in my bathroom, there's a book, Machine Learning for Idiots. Whenever I get a break, I'm reading it."

Cuban isn't learning about artificial intelligence out of pure boredom, however. Rather, he is excited about investing in AI, and says its importance in our world is only going to get bigger, and, "As big as PCs were an impact, as big as the internet was," he says, "AI is just going to dwarf it."

Artificial intelligence is what allows machines to process data, recognize patterns, and ultimately learn from experience. Because of it, computers can make adjustments and perform tasks just like humans can. Self-driving cars and the field of automation rely heavily on artificial intelligence -- existing products can be improved with AI capabilities, and these capabilities are what make virtual assistants (like Amazon's Alexa) or search engines (like Google) incredibly accurate.

Even if you don't work in tech, Cuban advises getting familiar with AI. He explains,

There'll be a time when people take AI and its impact for granted, but if you don't know how to use it and you don't understand it and you can't at least have a basic understanding of the different approaches and how the algorithms work, you can be blindsided in ways you couldn't even possibly imagine.

In particular, Cuban believes certain jobs could be displaced due to shifts that favor using AI. "We are going through the process where software will automate software, automation will automate automation," he told one audience at SXSW in 2017. Research even shows that by 2026, one million jobs in the US are expected to disappear because of automation.

Cuban, a self-made billionaire, knows a thing or two about making money. If you want to stay ahead of the curve as an employer, employee, or future entrepreneur, heed his words: "I am telling you...the world's first trillionaires are going to come from somebody who masters AI and all its derivatives, and applies it in ways we never thought of."
