I agree, but the solution isn&#x27;t to throw out the protocols we have. The solution is to use wired interfaces where appropriate. A light socket doesn&#x27;t move. It&#x27;s harder to replace the socket than the bulb, but the best long term solution is to replace the socket with a socket with an Ethernet port as well as a power connection.<p>I recently started a job at a company that produced Bluetooth chips. I&#x27;m currently about a quarter of the way through reading the entire Bluetooth spec. It&#x27;s 3000 pages long, incredibly complex, and most of the complexity goes to ensuring reliable secure communication. It&#x27;s not easy to just come up with a new wireless protocol that &quot;just works&quot;.
