Would it have any meaning to deal with (a) and to some extent, (b) by considering the stock founders at their last investment after a certain number of years (say, 5 or 10)?

Does this mean you see YC more as competing with other investors and less with graduate programs (I think I recall you mentioning that on some old thread).
