15 brains submerged in saline fluid, all linked up to one brain, also submerged in saline fluid so as not to feel left out, in the centre of the room. Happy brains, no concerns. You can imagine that?
Your naive self wanders in and questions brain one.
: What do you know, Mr. Brain number 1?
Mr. Brain 1
: I know everything every other brain knows.
: That is curious!
You move onto the next brain in the line, not believing the nonsense brain number one is telling you.
: Please Mr. Brain 2, if you will, tell me what colour the sky is?
Mr. Brain 2
: Why of course, dear child! It is green. Don't you know?
: Oh, I do know! However, that is wrong.
After questioning 2 brains you're becoming frustrated. You move onto the third brain the line.
Please, please. Do not play with me! What colour is the sky, if I may inquire?
Mr. Brain 3
: It is green, of course! Has anybody told you any differently?
: You all tell me the same. You're all wrong. Why do you tell me lies?
Mr. Brain 3
: We do no such thing, tactless child! You see, we are all linked to the brain in the centre of the room. Do you see it? Well, if you ask the same question, you get the same response. That is because our information is stored there in that brain, not here locally, what you see.
: Oh my! Muchas gracias, mi amigo!
! I thought I would carry on the skit there. See, if you ask the same question, because in a sense if $szVar1 is referenced to $szVar2 then they're accessing the same information. The information exists only once, and 2 or more variables access that.
If the brain in the centre of the room says the sky is green, and all subordinate brains are referencing that one single point, then the answer will always be green. If somebody tells the central brain the sky is now orange, all child brains will consider that so.
The child brains hold no data, they are gateways to what's in the mind of the parent. If you change the parent via the child (the gateway) then each child takes on that new information also. It is a consensus.
The man who comes back through the Door in the Wall will never be quite the same as the man who went out.
