It reminds me of OpenDoc, which, for the extremely limited set of tech demos that worked (e.g. putting the BBEdit text editor into any app that edited text) was awesome and flabbergasting when I saw it. Just because it failed and nobody has so far ever succeeded in delivering on that concept in a usable form doesn’t me we should just give up and go back to living in caves. It also doesn’t mean that developers who deliver on that only in limited-but-useful ways should be dismissed because they also failed to deliver the comprehensive universal successful implementation of it.
