Ted's needlessly authoritarian on implementation details, down to very specific details in file formats and how the components interact with each other using protocols that simply do not work.
For instance, he was insisting on ASCII only, byte addressed implementation of a cross referencing system with me in 2014 for the Xanadu implementation you mentioned. I couldn't convince him that multibyte encoding systems were worth considering or that offsets would change leading to fundamental data inconsistencies, thus corrupting formats...the rabbit hole gets deep. He gets very opinionated on details that don't matter and frankly don't work.
Thus it could only ever be a demo because you can't just feed open formats from the open internet it in any dynamic organic way. Everything would have to be curated, filtered, and babysat. That's not memex, that's some digital form of Pearson publishing with some proprietary e-reading system. Which is fine, but TBLs W3 system of intentionally leaving things open ended so every step becomes a potential platform for the next is so much dramatically better then just a cathedral cross referential monolith hybrid of hypercard and pdf. The brilliance of TBL is the W3 is half assed in just the right ways to make it not yet another unused visual language or mind map format. Should more be done? Sure, of course.
You may think it sounds absurd that Ted thinks there will be manual publishing under some private company's direction in the new format and not automated machine transliteration, I agree, it sounds like an archaic museum piece at the living computer museum in Seattle and not a future oriented system of thought. Well here we are anyway.
He needs to cede ground and intentionally leave pieces open ended so that other groups, in other cultures, with other priorities can fit in their specialized pieces into the puzzle. He apparently is still unwilling.
He's a brilliant philosopher but a classically toxic engineer. Usually that second group is full of people with bad ideas. His are undoubtedly revolutionary and profound, but the delegation of other thought systems to other humans and then interacting with them is like Drucker management 101 and he's just not onboard.
Also, without going into detail Andrew is a backstabbing ass. I hope he reads this and I'll state that publicly.
PS: In case Ted sees this (he probably still doesn't browse hn, but he gets forwarded things), I love you, you know this. You know my criticisms comes from a desire to make the acts as revolutionary as the thought and I want it to happen as much as you do. Hope to hear from you and hope all is well.
