I think you can love more than one child, and we've got to do all these at once. I think there's a store inventory opportunity for us and buying and selling merchandise is hard, by the way. There's a lot of people here that have been doing it for a long time and they're good at it, thankfully, but it's not easy.

I think scale matters, and being an Aggregator creates lots of opportunity, but scale also has a lot of disadvantages and it's an imperfect concept.

There are times when we want to own that inventory because we want a great customer experience, or we can take advantage of the amount of quantity we'll buy.

By the time we got to 2020, we had leaders that had a stronger digital acumen, e-commerce set of capabilities and beliefs.

I've drank all the Kool-Aid and am completely convinced that Walmart should be here for the next generation of retail, because we're so wired to fulfill our purpose of helping people save money and live better.

E-commerce had become so big and the plan was moving along such that you can't undo it now, you can make it better, you can plus it up, you can find some synergies and remove some of the older problems we had of the separation, but it created some newer problems and some complexity on how you actually integrate a supply chain, for example.
