Stanford's, MIT's, Dartmouth's symbolic AI social circle actively ruined (e.g. Rosenblatt's fate, sidelining Solomonoff's theory of learning) the credibility of nascent connectionist developments, likely stalling the progress by more than a decade. The institutions were afraid to give grants for connectionist research for the most of the second half of XX century. It's a pretty damning piece of history.
