It's a more prevalent problem at smaller nodes, but it's a general hyperscale problem. Modern datacenter CPUs are simply too complex to fully validate without increasing the cost so much that you're not competitive any more. Hyperscaling is very an exercise in thinking probabilistically. Everything fails without telling you, and that needs to be accounted for. It sort of approaches synthetic biology that way.
