Who is Bill from The New Way Things Work and what is their importance?

Bill is head of the Digital Domain and an enthusiastic entrepreneur. He reminds his co-workers of Bill Gates of Microsoft, one of the clear leaders in the field of computer technology. The fact that Bill, in the story, considers apples, the actual fruit, "rather low-tech and behind the times" seems to back up the play on Microsoft and its top competitor, Apple Industries. He is certain that the mammoth will be as excited as he himself is with the tour of the digital domain. What seems fast and confusing to the mammoth only continues to feed Bill's excitement and ingenuity. Bill sees the relevance and usefulness of his creations and seems to sincerely want to share their advances to create happiness for the Last Mammoth. Despite his best intentions, Bill fails to convince the mammoth of the glory of the Digital Domain. Bill is smart enough to see that, but the shrewd business man he is notes that the mammoth will return, not for the technology, but because the swamp grass is dying out the mammoth will need Bill's apples and pumpkins to survive.
