Interesting remark. I make the same calculation as yours and I also find that there currently is 1000 servers per million inhabitants on Earth today (between Amazon, Rackspace, MS and DO). In other words, one server serves 1,000 inhabitants. But given that not everyone has access to technology, let alone pay for Cloud services, I've estimated that we've provisioned 1 servers to serve all online services (bank, electricity, govt, OSS, Netflix, Volkswagen software, etc) for 100 citizen in developed areas. It's an extremely bad, resource-intensive architecture ;) The number of servers in private companies might be around 1 per citizen, and the number of processors per human around 100x (incl. mobile phone, tv, smart lamps). Given a proc has 5m transistors and humans have 100m neurons... our architecture is so bad that we're already outnumbered by machines by a factor of 20 at least.
