You might end up multiplying the same information thus creating volume but not variety. The scarcity of the information is the value, you can’t “make more”. If your text makes 500 distinct claims, expanding it 10x gives you those same 500 claims expressed 10 different ways, not 5,000 claims. It can help make it more robust to context, but it won't get amplified. It’s why contrarian thinkers are both valuable and drowned out.
