This paper that improves clock synchronization accuracy to tens of nanoseconds is amazing work. What changes with that level of accuracy? Like the paper says, Spanner commit times get a lot shorter. But is it now safe to take action without coordination? https://www.usenix.org/system/files/conference/nsdi18/nsdi18-geng.pdf …

It’s a very nice paper that advances the tightness that can be achieved with clock synchronization. Don’t think by itself it makes agreement and durability obsolete.

I agree in the strict sense, but I wonder how close we are to practically being able to appeal to probabilistic arguments about the chances of A and B having observed the same instant.
