I didn't realize that was up for debate. But I suppose in 2006, not everyone agreed that Google was killing Yahoo ("but what about their xyz, it's so much better than Google's xyz!!!").
In the last 5 years alone, AMZN grew 4x faster than WMT. For two direct competitors with a 4x difference in growth rate, how do you think the story ends?
So I presume the message is Amazon cannot be compared to Walmart because it’s much smaller? I love xkcd but this one left me confused because amzn’s market cap is 4x larger than wmt’s. So 4x larger and 4x faster growing.
