Andy Jassy: We exist to make customers' lives better and easier every day. I think we have very compelling customer experiences today, but they're a shadow of what they'll be 10 years from now. He says in our retail business, you're going to be able to get any item you can imagine. And then there's new things such as drones that will help connect 300-400 million people who don't have connectivity on the internet. 'If there's ever a customer experience that needs reinvention, particularly in the US, it's healthcare,' he adds.
