Eh, the example you give provides a domain-specific justification (avoiding confusion about the implied meaning). OP's problem doesn't really have this justification, and the perceived similarity of NIG() and that "N-word" is relatively silly and distracting to point out.

@BlueWizard the limits to computing can also be taken as the practical limits. If a task would take eons with traditional computers, it is beyond those limits, despite being theoretically possible.

@jkej °F redefined.

@paulgarrett it's also the fact that the goal technically is not to pass the exam, but to learn and apply the contents of the topic. This will not be achieved, when student simply memorize every answer, as many would(and that will hurt them later on, when understanding the topic is needed and not the specific answer to a specific question - it might be the same question, but you do not recognize it).

@AaronHall while that is true, there is no point in only focusing on the far future and forgetting the here and now, which is the point of the quote. I think that it should not be seen as advocating unbounded hedonism, hence the curt and dry wording. But, yes, it tends to be misused a bit.

Sometimes the silly question exposes a misunderstanding of an underlying fact, which can be hard to clear up when doing the research yourself (because you still search in the wrong direction due to your misconceptions). This will prolong searches endlessly. So yes, you should ask after trying to come up with the answer yourself, it will save time for both of you.
