Scott Aaronson, ["PHYS771 Lecture 14: Skepticism of Quantum Computing"](http://www.scottaaronson.com/democritus/lec14.html):
> The entire content of the Threshold Theorem is that you're correcting errors faster than they're created. That's the whole point, and the whole non-trivial thing that the theorem shows. That's the problem it solves.
