Apologies for asking a question unrelated to the message of the article, but I'm a bit confused by the use of 'discomfited' in the first sentence. From my understanding, 'discomforted' seems more accurate, and is a more commonly used word anyways.

Do I misunderstand the difference between discomfit and discomfort, or did they use the wrong word?

EDIT: I suppose it might just be a matter of wanting to come across sophisticated. At a later point the article uses 'insoluble' where 'unsolvable' would've been perfectly fine and probably easier to understand for most people.
