Considering the context I think it's worth pointing out that it's technically not impossible - it's just even less likely.

Everything in crypto is always a probability - never a certainty

True, but it makes the specific collision the post observed completely impossible.

I left a more detailed comment on the parent, but it's definitely not impossible!

The scenario in this post is that the first uuid was created one year before the duplicate uuid. That isn’t possible with v7

You're heavily leaning on "collision like this" to relate to the exact time stamps for your statement to be true.

It's equality possible to interpret the "like this" to the collision itself, without a focus on the 1 year distance between the creation dates.

So I guess both views are valid.

Surely the scenario where he generates the same number of items as he did between 2025 and now, but did it in 1 tick of v7 UUIDs also runs into it?

The scenario being the collision itself, the time period isn’t particularly relevant aside from it occurring much quicker than expected.
