I plan to discuss the importance of multicast and DIS during the symposium,
but a more interesting behavior problem is sports - let's say a football pass -
how do we decide "who caught the ball."
Yes network latency is involved. It's up to us now, Jan.
The championship is on the line with this pass.
Here are some choices:
- the receiver (no, really, he's very honest)
- the defender
- the ball (just another entity mate)
- the safety, breaking up the play
- the referee
- the other referee
- the passer (best view of the play, assuming he is still standing)
- the videotape (rollback)
- the other videotape (rollback from another point in time)
- Judge Ito and at least 2 teams of lawyers
- the coaches know the game and players best, let them decide
- you, since you have $100 riding on the game
- the guy next to you who is 2m tall, drunk and has $1000 on the other team
- the home team (they have all the market share)
- random coin (ah but who's coin do we use)
- random fan in the stadium (someone's mom perhaps)
- is God a fan?
Have you decided? Got another choice? Gesat. Now let's get all of
the other 100,000 fans in the stadium to agree, the 1M viewers on the
TV network to agree, and we'll follow that rule from now on. Hardly
likely we'll all agree... guess that's part of the appeal, keeps things
"interesting."
Here's my point: there are a lot of views of what reality is.
There's only one view that seems certainly wrong, it's when we say there is
only one rule and no others. Of course we may need one rule at a time
(so this individual game can proceed) but rules have been known to change.
Especially when we get smarter about what we are doing or neat cheats
are found. Behaviors in V_R_ML will work when a number of approaches to
_R_eality are possible.
Other conclusions will undoubtedly follow. That's the same point.
I'll jump off the soapbox now and wait for my turn later. See you in
San Diego.
all the best, Don
