Ivy's aren't the top schools for stem. MIT/Stanford/CMU are where the stem geniuses want to be, and after that the top public schools are probably more desirable than ivys because they're so much cheaper. I went to UIUC cs over uchicago and northwestern because of the price differential. By far the largest value ad ivys provide is networking with the soon to be rich and powerful. Seems like aspiring stem students realize that's not as important in their field.
