alt Hacker News> This is trying to solve a business problem (I can't trust cloud-providers) with a technical trade-off (avoid centralized architecture).
I don't think that's quite correct. I think the authors fully acknowledge that the business case for local-first is not complexly solved and is a closely related problem. These issues need both a business and technical solution, and the paper proposes a set of characteristics of what a solution could look like.
It's also incorrect to suggest that local-first is an argument for decentralisation - Martin Kleppmann has explicitly stated that he doesn't think decentralised tech solves these issues in a way that could become mass market. He is a proponent of centralised standardised sync engines that enable the ideals of local-first. See his talk from Local-first conf last year: https://youtu.be/NMq0vncHJvU?si=ilsQqIAncq0sBW95
I'm sure I'm missing a lot, but the paper is proposing CRDTs (Conflict-free Replicated Data Types) as the way to get all seven checkmarks. That is fundamentally a distributed solution, not a centralized one (since you don't need CRDTs if you have a central server).
And while they spend a lot of time on CRDTs as a technical solution, I didn't see any suggestions for business model solutions.
In fact, if we had a business model solution--particularly one where your data is not tied to a specific cloud-vendor--then decentralization would not be needed.
I get that they are trying to solve multiple problems with CDRTs (such a latency and offline support) but in my experience (we did this with Groove in the early 2000s) the trade-offs are too big for average users.
Tech has improved since then, of course, so maybe it will work this time.
