That's true, and yet the evidence shows that some companies have been able to do it. I think there's something to be learned by studying those companies as a data set.
They have been able to "so far". This isn't to say that we shouldn't learn from them how to push the failure date as far into the future as you can. I just don't think you can truly make something incorruptible.
It’s perhaps idealistic, but maybe we’ll figure out a way to limit the blast radius of any failures by driving a culture that rewards those that push out the future date as you say
