Yes, I think vision of Nobel prize has changed with years. Now it's mostly regarded as avery prestigious mark to put on "best of the best" but originally it was probably not just award for achievements but a way to distribute money to the people who can really use it to advance science, it's a way to choose from all the people, those who can use the money effectively. That's why they don't award Nobel Prize to dead people, because they can't use those money to advance science any more. And also that's probably why they added a rule to wait for some time before awarding the prize - to check that this achievement is real and person or persons who are related to it can be trusted.
