Was there some dispute I didn't hear about? I'm pretty sure everyone knows that MIT is pretty great. Did Gates just copy-paste info from the recruitment packet? I suspect that if this was not written by Bill Gates, it would have never made it to the front page of HN.
I might be wrong, but haven't there been some talk about MIT not getting the funding they used to? I.e. maybe it's not aimed at the already converted?
Then "At night, the ice weasels come", or the Great Recession wacked a good part of their endowment like most ever other institution like MIT. They didn't get caught out like Harvard but it's caused a lot of problems, e.g. last time I checked freezing the conversion of the old graduate student dorm into a refurbished undergraduate dorm.
