AI will continue to transform our homes. One of the most prolific uses of AI can be found in the humble smart speakers that nearly one-quarter of Americans have in their homes. It's become increasingly clear that tech companies look to these AI assistants to create new sources of revenue. For example, Amazon's Echo speakers allow people to easily buy products from its website through voice commands, and recent data shows that Amazon Prime members spend $400 more on the company's site if they own an Echo speaker than members who don't have one. Amazon could add $10 billion to its top line by 2020 thanks to the company's sales through its smart speakers, according to RBC Capital Market predictions.
