So is the likelihood of literally everyone else's existence...
So what?
If I'm at a poker table, should I not bother to look at my cards, because everyone else has cards too?
You'll need to do better than that, to be as "coherent" as you demand that I be.
This is me being more coherent than you. Giving an actual example of how following your blanket denial of conditional probability would be stupid and costly.
Well, no. It's not. Because it is an exceptionally obvious objection to Jabba's argument which, despite the fact that it has apparently stuck in your craw for no apparent reason, neither you nor he has managed to produce a coherent objection to.
Analogy: You claim I owe you 50 bucks. I pull out a die, roll it, and exclaim "so what" when it stops rolling.
What is your "coherent" response?
Claiming I still owe you 50 bucks isn't going to work. I'll just roll the die and exclaim "so what" again.
See what your main problem is now? Your main problem is not forging a coherent response. Your main problem is coming up with
any response, short of abject surrender, which would have any positive effect at all on the Blanket Denial Corps, and therefore not be a waste of time and labor.
No matter how unlikely any given result of that die roll is, one of them has got to come up.
But what if you have been kidnapped, and your captors hand you a 10
80! - sided die, and tell you to roll a 1 or they'll killl you before you can say "so what" when it stops rolling.
Ruh-roh...all of a sudden the situation got all conditionally dependent. Now that it's your specific ass on the line, and not just "some number". But not to worry. You roll the freaking 1.
And of course it would
never occur to you that the game was rigged and your captors were just messing with you, right? It's far more likely that you beat those 10
80! odds fair and square. Right? After all, no doubt many others throughout the universe have been in a similar bind and also beat similar odds. Right?
"So what", you say? I'll tell you so what. Unless the game
is rigged, you're dead. It doesn't matter how many other people may have beaten the big odds (assuming they weren't part of the rigged game). You, specifically, are dead unless that game
is rigged.
And I'll bet that you're dead in an unrigged game a trillion times in a row against those odds, and never sweat the outcome. I take orders of magnitude bigger risks every day, just puttering around doing everyday things.
Coherent response, please.
