Sure, the current draw per byte of information exchanged is negligible. But I'm curious as to how these millions of cheap, low-power IoT devices can essentially act as transistors in the sense that their requests can prompt more relatively higher current draw elsewhere. Once again, this draw is likely miniscule. In theory, if every internet connected device in the world could be a part of Mirai, not only would we not be able to use the internet, but wouldn't the majority of datacenters be running at full capacity?
