A software project that takes a year will costs a fortune (salaries are expensive). It will probably have to be maintained and running for the next decades to give enough returns to be worthwhile. So, 1 year is the time the first interns team will work on it, 10 year is the duration before the project is retired. Looks like both estimates were right.
