This is absolutely true. But two things: (1) Dan was already passionate about VisiCalc. It's not like he and Rich Franklin weren't particularly interested in numbers but thought they could save accountants a few bucks a day. And (2) You are describing something that might transform someone's job or disrupt an industry. That's very motivational. But this is not the same thing as "Hey, someone might pay a few bucks for these crud operations." The ideal business is one where (a) you are already motivated by the subject matter, 2) you will transform somebody else's life or business, and III. they are willing to pay for it.
