A truly wireless future?

It is argued that wires are an endangered species. They are vanishing from our environment. The author notes that if there was one place he would have thought we would always find wires, it would be on-chip. But as we see in this special issue of Design & Test wireless Networks on Chip are possible, so we may not even find long wires there in the future. What has created this wire-free revolution? Two things: better batteries and small and ubiquitous radio transmitters and receivers.
