I see this quote often, but it hasn't really panned out for Amazon in practice. I see other large tech companies (Google, Apple, Facebook) with these huge profit margins every quarter, year after year. Amazon has never made a dent in any of them, nor made a sizable profit themselves, despite all of that "opportunity." Perhaps he's not speaking of tech but of retail, in which case the margins of companies like Walmart are already incredibly tight.
