GELERNTER_LOST_MIRRORS

                                             September 20, 2026


I've seen some comments to the effect that David Gelernter
was ahead of his time, fore-shadowing the development of the
world-wide web in a book written in 1992, "Mirror Worlds".

Now, that's not actually much of a lead time.  A lot of us had
been messing with the internet for years at that point, and a lot
of us were thinking about how we were going to get to something
like Ted Nelson's "Grand Hypertext".  I remember playing with
gopher when it was invented in 1991, and I tried Archie briefly.
And really, Tim Berners-Lee came up with http back in 1989.

But "Mirror Worlds" was a book written before Gelernter survived
a unabomber attack-- maybe he hadn't gotten quite so crazy yet?

   "Mirror Worlds?"

   "What *are* they?"

   "They are software models of some chunk of reality,
   some piece of the *real world* going on outside your window.
   Oceans of information pour endlessly into the model
   (through a vast maze of software pipes andh oses): so much
   information that *the model* can mimic *the reality's* every
   move, moment-by-moment.



   "What's the point?  These Mirror Worlds are like regular
   old-fashioned databases, to some extent.  ... But they
   go far beyond this.  The Mirror World is directly
   accessible, twenty-four hours a day, to the population
   it tracks.  You can parachute in your own software agents.
   They look out for your interests, or gather data that you
   need, or let you know when something significant is going on.
   You consult the Mirror World like an encyclopaedia when you
   need information; you read it like a dashboard when you need
   a fast take on current status.  Fundamentally these
   programs are intended to help you *comprehend* the
   powerful, super-techno-glossy, dangerously complicated
   and basically indifferent man-mad environments that emesh
   you, and that control you to the extent that you don't
   control them."

   "So Mirror Worlds function *in part* as fire walls opposing the
   onslaught of chaos.  But they aren't *mere* fire breaks.
   They are beer halls and grand piazzas, natrual gathering places
   for information hunters and insight searchers.  Most important,
   they are *microcosms*-- intricate worlds come alive in small
   packages."


So, "mirror worlds":

Virtual reality, AI agents, databases, maybe
a touch of networked information exchange,         And oceans of vast
ala the WWW and wikipedia.                         mazes that
                                                   parachute into the
                                                   super-techno-glossy...




There are problems he's ignoring here: to have some
agent defend *your* interests and behave under
*your* control, without trusting the good-will and
competence of some software designers and operating
companies would be a good trick.  It also presumes
you know what your interests are and have some idea
of how to watch out for them, which is another set
of non-trivial problems.

    Any database can already be made "directly
    accessible, twenty-four hours a day, to the
    population it tracks"-- if they're not set up that
    way it's because the people who set them up don't
    want them to be.

       You can't just go "far beyond" what are essentially
       social problems with a wave of some magic software.

    But I note though that using a VR as a *model* has a
    different style of thinking than Willam Gibson's
    notion of VR, where the real world and the parallel
    software constructs are so tightly connected you can
    think of them as identical.

    Thinking of a VR as a model allows for things like
    the training sessions in "The Matrix" (1999), where
    you can do things experimentally to see if they
    work, and roll back to the initial state whenever
    you need to.
