Did you click through to the video? Because the acceptance speech seemed to show the opposite of hubris to me. Specifically in owning up to the mistake, and using the award as a reminder to do better in the future.
If anything, his attitude of (paraphrasing) “we accept this; we screwed up, and we will prominently display it as a reminder to our staff to never let this happen again” was about the best response he could’ve given.
As an attorney, I’ve made mistakes and screwed things up. The initial instinct is to be less than candid and not admit anything. Then, after a sweaty sleepless night, I bit the bullet and was open and honest with the client, admitted fault, apologized, and offered to do what I could to make it right. Every reptilian synapse was screaming “don’t do it,” but it was the right thing to do, and I have no doubt, cost me much less in the end.
