Estimates are for projects where you know what you're doing. You can estimate home construction because you've built a home before.
I can estimate the happy path. I can't estimate edge and corner cases until I get closer to the edge or corner. It's not even there until I get close to it.
I strongly agree with these statements from the article:
>"Tasks with the most uncertainty (rather the biggest size) can often dominate the mean time it takes to complete all tasks.
The mean time to complete a task we know nothing about is actually infinite."
