There are 2000 cities in the country. Every city is connected by non-stop two-way airlines with some other cities, and for each city, the number of airlines originating from it is a factor of two. (i.e. $1$, $2$, $4$, $8$, $...$). For each city $A$, the statistician calculated the number routes with no more than one transfer connecting $A$ with other cities, and then summed up the results for all $2000$ cities. He got $100,000$. Prove that the statistician was wrong.
