thats a strange assertion when the internet was famously invented to eliminate complex failure modes. Quoting from "DARPA and the Internet Revolution" By Mitch Waldrop [0] "Finally, Roberts decided to make the network completely decentralized, with no one master computer responsible for sorting the packets and routing them to their destination. Such a Grand Central Station approach would have been much simpler to implement, Roberts knew. But one blown transistor could have taken the whole network down. So instead, he decreed that the ARPA sites would be linked in a complex pattern rather like the Interstate highway map, and that each site would share the routing responsibilities equally. That is, the computer there would read the digital address on each packet as it came in, accept that packet if the address was local, or else send it off again on the next stage of its journey. This “packet-switching” approach would mean more complexity and more programming during the set-up phase. But the final system would be far more robust: No one failure could bring it down."
