The real purpose of a Fermi estimate isn't to give you solid answers:
it's to give you an appreciation of the problem. If it does that, it's
done its job.

Does anything prevent the key breaker getting lucky and cracking it first try?
No. It's just extremely unlikely.
It seems to me that all discussions on key breaking with their very large
numbers always assume that the last try is THE ONE.
Nu,
A while ago Hauke asked if the statement in the FAQ about a brute-forcer
leaving the Earth uninhabitable was correct. I said it was, but I
didn't break out the math. Now that I have a few minutes to breathe,

10 billion is 10**10, so it takes 10**20 times the age of the universe.
