We lose knowledge all the time. Every person that dies carries a lifetime of experiences and information.
The thing is, we tend to lose the knowledge that is deemed useless. Anything considered useful is well spread. The problem is when our opinion doesn't match the reality, we have something around a generation to prove it, or the chance is gone.
Mathematics is full of examples of things that were discovered again and again, until somebody found a use for them and they entered our textbooks.
