- The problem I have with this analogy is this: what it sounds like to
- me is that the crudest bicycle was actually DID look somewhat like
- bicycles do today (two wheels, a frame) and WAS quite useful, and that
- therefore the process of refinement of bicycles started (and continues
- today).
-
- VR, by contrast, started with umpteen million dollar flight simulators
- (as the major application, anyway), and was useful to a very small
- market that would either have had to pay much more or take much
- greater risks to get a similar degree of utility out of any other
- scheme.
-
- Thus my gripe with VR: where the hell is my crude-bicycle version of
- it that I can use to get around?
-
- And let's not forget another thing: get around WHERE and via WHAT?
- The ultimate technology of civilization was not the WHEEL, which was
- invented and reinvented for use in toys by countless generations in
- many civilizations long past, without getting used for real work.
- Civilization (civitas="City" -> "City-ization") comes about when you
- have ROADS. The wheel is but a refinement step on the civil
- engineering accomplishment of the built road.
-
- You can have 30 zillion polygons-per-second in your VR apparatus and
- all your really doing is sniffing at a pseudo-psychedelic blossom
- growing out of your walking stick as you travel down the muddy goat
- path of the current VR infrastructure.
-
- High connectivity coupled with object-representation standards is
- needed to bootstrap this VR infrastructure. This doesn't require
- real-time 3D binocular rendering at the terminus. You can, instead,
- use an already widespread "bicycle" technology -- the personal
- computer. --- Michael Turner miket@tcs.com

- [MODERATOR'S NOTE: Gee, Mike, will you not be so wishy-washy: speak
- right up! :-) Actually, there's a lot the average personal computer
- cannot do...and why on earth would anyone want to travel a muddy goat
- path? Perhaps the onset of sci.virtual-worlds.apps will help to dispel
- some notions...speaking of which, it's ALMOST here. -- Bob Jacobson]
