It's good to be able to have cultural diffusion. And when you have a big butt mountain range on your right shoulder, you're not going to have a lot of that. So you're going to live in isolationism. You'll be safe, but you're not going to modernize, you're not going to develop. Not only that, but if you think about how geography can do that, what's on their other shoulder? The Pacific Ocean. So they're trapped by barriers.
