You're right and my comment made it seem like everyone has some grudge or something. I think in general the PARC community was weary that the takeaways would be centered around how computers, GUI, etc. were great ways of doing old things better (accounting, reading text, etc) instead of being captivated by computing as a medium for thinking. This happened with print, as Alan has discussed in some of his talks. The first 100 years of print was used to print and distributed religious text and it took a while before ideas that could probably only sprout in the print medium were invented (physics, calculus, some philosophies, etc). To some degree, I think some people feel like we're still in the "use print for spreading religious text" phase (or the "film is a great way of recording & distributing plays" phase.
