It's disingenuous to suggest that "Yjs will completely destroy and re-create the entire document on every single keystroke" and that this is "by design" of Yjs. This is a design limitation of the official y-Prosemirror bindings that are integrating two distinct (and complex) projects. The post is implying that this is a flaw in the core Yjs library and an issue with CRDTs as a whole. This is not the case.
It is very true that there are nuances you have to deal with when using CRDT toolkits like Yjs and Automerge - the merged state is "correct" as a structure, but may not match your scheme. You have to deal with that into your application (Prosemirror does this for you, if you want it, and can live with the invalid nodes being removed)
You can't have your cake and eat it with CRDTs, just as you can't with OT. Both come with compromises and complexities. Your job as a developer is to weigh them for the use case you are designing for.
One area in particular that I feel CRDTs may really shine is in agentic systems. The ability to fork+merge at will is incredibly important for async long running tasks. You can validate the state after an agent has worked, and then decide to merge to main or not. Long running forks are more complex to achieve with OT.
There is some good content in this post, but it's leaning a little too far towards drama creation for my tast.
