Considering the fact that what we don't know is potentially infinite, and what we don't know we don't know is a potentially infinite chunk of that, how could that ever be true? :-)

Well, I guess we could hit a local minima where we need some out-of-this-world resources or research to level up, but let's not be so pessimistic so soon. We've only been doing this modern research thing for a few centuries. You could go back 4-5 generations in an especially long lived family and you'd find someone in the family tree that was still alive before the modern scientific method was created.
