3 Best Artificial Intelligence Stocks to Buy Now

Alphabet's Google is arguably the first mover in using AI among its "big tech" peers -- a category from which I'm excluding IBM, which arrived early to the AI party. The company has been pouring massive sums of money into infusing AI -- particularly machine learning -- into its products and services. For instance, in its core search business, Google uses AI to improve the relevancy of the ads it shows users, and on YouTube, it employs AI to serve up music and video selections based on a users' previous listening and viewing habits. Like Amazon and Apple, the company also has an AI-powered smart assistant: Google Assistant started out its life helping Android-powered smartphone users, and is also now incorporated into the company's smart speaker, Google Home.
