If statements like this were a habit of his, I'd agree.
Here it sound a bit more like part of a farewell address, but with more to show than Mr. Gelsinger and fewer of such public statements in the past.
At that point at worst I'd call it more pride than arrogance, and while any advice from a mountain of success doesn't guarantee equal succes for anyone that follows it, anyone else quite literally hasn't ascended to that same level and has too look up to him looking down, even with a guy that isn't very tall.
