Yup. My friend is a high school teacher, and he did the same thing to his class - told them not to use Wikipedia, but that Wikipedia sources were fine, and the kids did actual research.

Hardly a loophole - Wikipedia’s greatest strength is as an aggregator of reliable information, and using Wikipedia’s sources is how people SHOULD use it. They just taught you how to use it.

You’re not - it’s pretty explicitly the point. The technological arms race has gotten so advanced that everyone has devolved into fighting with knives.

Aren’t wind turbine blades fiberglass? Can fiberglass be printed?
