I bet you that over time, because we come up with new ideas to grow sales, we end up with about the same number of people making more money.

I think most Americans probably don't know what a tech makes that helps take care of our stores and clubs and that we can help them learn how to be a tech. The same thing's true for our drivers. So we have a need to get the word out so that people know there are some great jobs.

As I look across our company, we have everything from store associates to supply chain associates. Of the 2.1 million people (globally), something less than 75,000 of them are home office jobs. All the other ones are working in a store, a club, a distribution center. And I think those jobs change more gradually. We are still going to want to serve customers and members with people. The change as it relates to the home office jobs probably happens faster.

I think no one knows how this is going to play out exactly. And the way it feels to me is that basically every job gets changed. And I think the best way to think about it is getting "plussed up." So how can I lean in the role that I have, regardless what that role is, to adopt new tools, leverage them and make things better than they would've otherwise been?

Until we're serving humanoid robots and they have the ability to spend money, we're serving people. We're going to put people in front of people.

One of the biggest areas of change in the last decade is related to associates that work in our stores, picking orders for delivery and pickup for our customers. And we have something north of 200,000 people doing that job, and yet we have about the same (total) number of people working in Walmart U.S.
