Actually I can and have system engineered ultra-reliable production systems which ran over ten years without issues: I'd come back to work at a former employer and the system would still be there, serving. This was not an isolated scenario. One cannot build highly available systems and networks on unreliable, lying software. Basic guarantees are required. If one has 10,000 systems and one loses power on even a portion of such lying systems without basic guarantees, no amount of distribution will guarantee data consistency. I'm no stranger to building very large distributed clusters, but those builds start with an operating system and software which do not overcommit and which are paranoid about data integrity and correctness of operation. In fact, I'm specialized in designing such networks and systems, from hardware to storage all the way up to application software.
