It doesn't seem like there's any major difference so it's interesting that latency is perceived as being a reason not to use blazor server in production but not as such with liveview.

The audience for Blazor Server is probably an order of magnitude larger than the audience for LiveView, and it's mostly not the Hacker News crowd that needs to be won over, but the large enterprise with half a million lines of Web Forms that has grown into an unmaintainable behemoth.

Inherent in any framework that uses a connection to transmit diffed DOM nodes.

yeah, that's what I thought. it's certainly the achilles heel of this technique.
