Telephones 1876 Electricity grid 1888 🤔 It is interesting how a decentralised grid, eg domestic solar could in theory dramatically increase a nations resilience to threats. That just leaves your ISP with a hand on the rug. I think a system of self-generated network address allocation could replace Internet Protocol, and there would be huge market drivers for speedy adoption. Imagine people self generate an IP, even if it took 5 seconds to establish a connection it would be a better fit to domestic network traffic than TCP/IP which is a warzone tech. Would probably require some kind of long range wifi though, to create a network fabric outside the cable infrastructure of the internet. The network equivalent of the solar panel. But again, this is well within the reach of engineering in 2023.
