The event horizon = singularity metaphor is a little off. There is no breakdown in the laws of physics at the event horizon. It's just that there is no light or matter that escapes from the event horizon. But the laws of physics don't break down until you reach the center of the black hole (which will happen in finite time after you cross the event horizon).

So there are a couple interesting and meaningful changes at the event horizon, but it's not a mathematical singularity.
