Technology empowers the less empowered. If there is a strong force that bring a change in the lives of those on the margins it is technology. It serves as a leveler and a springboard.

The Internet has been the most fundamental change during my lifetime and for hundreds of years.

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.

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.

What's dangerous is not to evolve, not to invent, not to improve the customer experience.

I think technology advanced faster than anticipated. In that whirlwind, a lot of companies didn't survive. The reason we have done well is because, even in that whirlwind, we kept heads-down focused on the customers. All the metrics that we can track about customers have improved every year.
