So on the one hand you have a direct statement from the source that the cause of this incident is humans. On the other hand, while we all agree there is no specific evidence that A…

> I'm not sure why people are so quick to discount [AI] as a potential source of the issue. Because (per the link above) the CEO said that (1) it was their fault, and (2) it had no…

The CEO says it's not: https://x.com/JustJake/status/2038799619640250864 A lot of people are confident in enough in their ability to spot AI infra that they are willing to dismiss …

> It feels a little weird to put 100 hours into something that won't be noticed by its absence. Exactly no one will think, "man this dithering is stable as shit. total magic going …

lol ok we can talk and record it. I want to make it clear that this is NOT a debate, though. I actually want to be convinced!

But Kevin, prosemirror-collab does give me offline editing. I use it literally every day, entirely without issue. I write offline on different devices, and whenever I come online, …

I run a VC-funded startup. We fund the extremely high-quality OSS `react-prosemirror` project at > $10k a year. I really, really think you should too. Here was our thinking: - Chea…

But Kevin, you never really answered the question of the article. Unless I need a truly-masterless p2p topology, why would I do all this stuff, including throw away editor intent a…

The magic of CRDTs does not prevent this. They are in exactly the same boat as OT, prosemirror-collab and prosemirror-collab-commit. It can't be prevented. The problem is worse wit…

I do not know how to say this another way. No. Nothing in this article was created, edited, outlined, pre-drafted, suggested, or in any other way influenced by AI. AI did not write…

Actually, I think I agree with most of this... except the part where you think it's not clear-cut, ha ha. I meant that not as a comparison between OT and CRDTs, but as a comparison…

Ok Marijn I understand. I'm sorry I caused you an inconvenience. Of course, I know that implementing server-side prosemirror-collab is not entirely without problems (since we have …

Just to be extremely clear: we pay for a lot of OSS software. We pay one individual project more than $10,000 a year. We would have paid for Yjs too, if we thought it was a good us…

Hi Joseph! Good to see you here. Sorry, I see why this was confusing. What I'm saying is that because users perceive the results of OT, CRDTs, prosemirror-collab, etc . as data cor…

Thanks Nick. I am aware. The blog post directly links to the PR you merged some days ago that (as I understand it) kicks off the effort. I also mention specifically I know you're w…

Just tying up loose ends here, in this other comment I suggest that Kevin and I are not on the same page about the point I was making in the article: https://news.ycombinator.com/i…

Hi Kevin, author here, are you sure we are on the same page about what I'm saying in this article? For example, the debugging section is NOT about debugging problems inside Yjs, it…

So, we are basically making two points. First, the fact that Yjs bindings, by design (for ~6 years), replace the entire document, does in my opinion, indicate a fundamental misunde…

I know it seems that way, but it's actually not 80% of the way to a CRDT because rich text CRDTs are an open research problem. Yjs instead models the document as an XML tree and th…

It might fix the replace-everything bug. It definitely does not fix any of the other issues I mentioned. Even just taking the permissions problem: Yjs is built for a truly p2p topo…

Hi Matt! Good to see you here. For those who don't know, Matt also wrote a blog about how to do ProseMirror sync without CRDTs or OT here: https://mattweidner.com/2025/05/21/text-w…

To be clear, we ARE arguing CRDTs needlessly complex for the centralized server use case. What I am describing in the "delete and replace all on every keystroke" problem is the poi…

First of all, thanks for chiming in! I wish someone would collect stuff like this and write it down in some sort of "oral history of collab editing." Second of all, I actually thin…

Author here, just chiming in to say that Matt has an actual PhD on the subject so rather than explain it worse, I will just let him say the probably-actually-correct thing here.

Great question. Matt has a comment about this here, and he has an actual PhD on the subject! So rather than doing a worse job explaining I will leave it to him to explain: https://…
