Before the movie started, I wasn't completely sure that I'd seen it. I definitely had memories of scenes, but that could be attributed to having been alive during the past couple decades and a tendency to fall into I ♥ the ____ marathons on VH1. At least now I have seen the whole thing, possibly more than once, and the potential void has been filled. Yet because of this uncertainty, I'm afraid that it isn't as much much a cultural touchstone to me as it seems to be to other people. I haven't read Steven Johnson's new book, but I'd guess that this could be used as an example of how much simpler entertainments were not too long ago.
This is not to say that I didn't enjoy it. Plus the experience of going to Fremont is always entertaining in itself.
