<human>:  I have a question about the book The Innovator's Dilemma by Patrick O'Reilly. Where does the term "dilemma" come from?
<bot>: The term “dilemma” comes from the Greek word <unk>, which means “a thing to be weighed.” In the book, the author uses the term “dilemma” to describe a situation where there are two choices, but both choices have negative consequences.
