This post buys into the common narrative about Xanadu, that it was a fundamentally good idea that failed due to some combination of poor execution, being too far ahead of its time, and the market not caring about quality (with this post in particular focusing mostly on the second thing).
In my view, Gwern makes a compelling counterargument: Xanadu was a fundamentally bad idea. The parts of it that weren't incorporated into the World Wide Web either solved problems no one actually had, or couldn't have constituted a stable equilibrium between users and publishers (i.e., even if it'd been magically willed into existence, it'd have quickly fallen apart). https://gwern.net/xanadu
This economic equilibrium reality kills so many cool-sounding ideas. Someone has to actually run them, and if it's more soul-sucking than soul-giving (for some definition of "soul" which may include money) it won't happen. It's not always money, sometimes it's just really hard to keep the service up or to block spam.
Great post, as a fan of Gwern and Nelson I wonder how I missed it (and how I didn’t get an invite to the party :’)
The “too genius, too early” is a common trope in the tech industry, but it rarely stands scrutiny. When you inspect the claim up close you almost inevitably find out a variation of that “bad design/solves a problem no one really has/does not create the virtuous cycles needed for success”.
But as an inventor it might be easier for one’s ego to tell yourself “i was just ahead of my time” than “my judgement was completely off”.
If you’re an inventor of any kind, the “try lots of small things, see which ones seem to stick, narrow down on those” approach seems preferable to “commit your entire identity to one big thing”, but there is a certain siren song to the latter.
