What's wrong with bringing those back to life? Their organizing features have been unmatched by any application we have today, except maybe wikis.
They didn't fail for not being useful, but because their engineering was clunky and their demands on resources were way beyond the hardware of the time. Also those systems were too complex for the classic programming techniques. Now that we have a better understanding of reactive programming and async dependencies, maybe we can finally build the tools ecosystem to take advantage of homoiconic data, and these systems can take off.
