Well. I suppose it is largely made disadvantageous by being at odds with someone else.

[ The cup completes its journey, and is set back down. ]

I have spent a great deal of time pursuing knowledge that another strongly prefers I not have, and I have sometime found the cost of that pursuit to myself or those I care for to far outweigh the benefit of whatever it is I gain by it.

A rare occurrence, for which I am most grateful, but it does mean I cannot rightly say seeking knowledge is never disadvantageous.
