I would have to disagree. One of the main benefits of distributed systems is that you don't need to know that in reality your file system is sharded on to 5 different disks at 2 different colocs. I understand that sometimes you need to manually recover, but OP sweepingly states that distributed systems is a UX problem, which I think is a ridiculous reduction and equivalent to saying "well this shit is hard so let's just spill the guts of the system internals up to the user"
