There is some art that says the same thing to everybody. WE need something like that. What that is, I don't know. But virtual reality may be the key to it.

I'll try any guitar just to see if it's different in an effort to see if it will lead me anywhere. I'm trying to have a guitar built. What's needed is better instruments, better amplifiers, better hardware for electric music to get better.

This virtual reality stuff is the technological equivalent, really, of psychedelics.

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 we've seen it all. The e-commerce store is the interesting one.

There are all these things that add up into this business that's Walmart that keeps it really interesting. At the root of it all, though, it's a people business and it's a merchandising business. Today, it's increasingly a technology business. The supply chain is critical, of course, and real estate still plays a key role.
