Best Buy will lose to Amazon, because Best Buy at best will be a big box retail store chain, with a online presence. The online division has to clear everything through the established big box retail store chain hierarchy. Further, they would be directly competing with themselves-- which may seem like a no-brainer and not a problem, but what do all those people in the big box retail store chain hierarchy think about no longer being relevant?

You could be right about Chevron, or Chevron could just be self aware enough to know they are better off delaying the shift, rather than trying to usher it in while competing against themselves.
