RIP Siri? You can use Alexa in Amazon's app now, and it's really smart

Amazon's digital assistant just landed on iOS, and it's giving Siri a run for its money. You can now talk to Alexa via Amazon's official shopping app. The update dropped Thursday for many users, and it provides answers to serious questions ("what is a black hole?"), along with terrible jokes ("Why did the chicken cross the playground? To get to the other slide") and, of course, shopping suggestions. Amazon says it'll be rolling out to everyone over the next week.
