Combating the Collosus of Worldly Knowledge- when do we reach the limit?

You mean for an individual, or for humanity as a whole?

Unless you know something (or claim to know something) which we don't, human intellectual expansion is the only intellectual expansion game in town.

Useless trivia will always need updating..

I don't know how you can say that. The longest serving officer in the Royal Navy was a Canadian, Provo Wallis, born in Nova Scotia in 1791, and died in England in 1892. He was first read into the Navy in 1796, as a ship's boy (the beginning of the career path for midshipman, from which one hoped to become an officer), and served for 96 years (77 years of that as a serving officer, 1800-1877). They ain't nothin' trivial about that!

I didn't know that, but to be fair it's kinda old news. It's the keeping up with Kardasians and all that crap that will go one forever..

Human intellectual expansion is a subjective differential from the past- it is futile to expect much from the human mind...
I doubt that you are a troll, as a subsidiary comment.
