Invention is not enough. Tesla invented the electric power we use, but he struggled to get it out to people. You have to combine both things: invention and innovation focus, plus the company that can commercialize things and get them to people.

For a lot of companies, it's useful for them to feel like they have an obvious competitor and to rally around that. I personally believe it's better to shoot higher. You don't want to be looking at your competitors. You want to be looking at what's possible and how to make the world better.

Looking ahead, we will compete with technology, but win with people. We will be people-led and tech-empowered.

One of the technology leaders, a few years ago, was visiting with me here and we were writing on the whiteboard and they stopped and turned around and looked at me and said, "Oh my God, you're going to win." And I said, "Yeah, but why?". "Now, tell me how".

I think that people that shop Walmart frequently and love the brand the most find it very natural to come to us first for e-commerce. But for others that may shop around or not have chosen to shop at Walmart in the past, you get what you earn, and our opportunity to earn their business starts with winning their grocery and consumables basket.

Nobody wants to buy a $60,000 electric Civic. But people will pay $90,000 for an electric sports car.
