- Why a collision?

> Because man made SHA-2, so it must be breakable. I don't dispute that there are systems humans make that are breakable (that would be weird given my career).

Thus implying there are man-made systems that are not breakable, and furthermore SHA-2 is one of them.

Going back so quickly?

I'm sorry, you've lost me. I was responding to the claim that any man-made system was breakable. The most obvious example of a man-made system that is unlikely to be breakable in our lifetimes (so, I'll say, "ever") is SHA2. Then someone responded that SHA2 wasn't an interesting target. It doesn't have to be; it just has to be man-made, or concede the narrowing of the original claim.

lmao at substituting “ever” for “in our lifetimes”

“That will never happen” and “I think I’ll die before that happens” aren’t interchangeable. Hydrogen will never have two protons, SHA-2 will be broken. “I personally don’t consider a future where I’m not around as existing” is like busting out an Uno reverse card when you lose a hand at poker

This objection doesn't make sense in the context of the thread.

[jrflowers]

It’s not an objection. Somebody said “[x thing] is impermanent” and the rebuttal you posted was “human life is also impermanent”

That’s not really a rebuttal to the notion that everything is impermanent, that supports it.

Anyway a wizened crone told me I’ll die on 11 September 2098, so let’s give me two weeks to gloat. Two weeks before that date. I will bet you that it happens on or before that date. Props for taking the over that no collisions of SHA-2 will happen before then

The danger of using quotation marks around things that aren't quotes is that you can wildly misstate what somebody said and readers are left to ponder if you just don't understand or if you're willfully trying to misrepresent them.

The reason a bet on this would need a date other than "ever" is because if one side of the bet can't be resolved until infinite time has passed, it just doesn't make any sense.

I wonder when Kalshi will start offering bets where one side doesn’t pay out until the end of the universe.
