When you’re building data centers, you are fully aware you are building “The Cloud” (even before that term was coined), because that’s literally the business you’re in … regardless of who you’re customer (AWS) is or not.
Is there a reason you're so intent on being a killjoy? Is there really an important point being made here? Don't worry, they do not falsely believe that they invented and built AWS.
This story is basically akin to someone who works at a restaurant saying that one day a celebrity came in and ordered a hamburger, and a photo was taken with the hamburger that ended up becoming famous, and them saying that they made that hamburger. It's just an interesting "I was a small part of something that became big" story. But thank god we have you here to make sure that that person doesn't go around telling people they built AWS.
No, because it says "without really knowing it" right in the first sentence.
