Agreed, 106%.

As Joe Armstrong, benelovent co-leader of the concurrent world, is fond
of saying, it takes at least two machines to detect and recover from a
fault in one.  In the larger case of split brain management in
distributed, asynchronous, message passing environment (like the
Universe), there are fundamental limits and impossibilities that nobody
is immune from.  Good luck with two machines figuring that out.
