Looks like Walmart will finally get it's ass moving. I think Amazon is getting too dominant as an organization. For the general good it needs a competitor to keep it in check. I hope Walmart can keep up. Beating up big brands to lower their prices is the side effect. Unfortunately, this means more automation for all, which means less jobs.
BTW, Bezos will be the richest man in the world within the next few years. Amazing what focus and determination can do.
