A bit offtopic but I was thinking that it might actually be possible for some companies to replace TCP/IP. Let's say Apple. They probably have enough money to do the SpaceX thing and have a network of satellites in orbit that could replace the mobile network all iPhones connect to worldwide. Since they control all the devices that connect to this network, they would have full control over the internet protocol it uses and could invent their own, from scratch. Actually, SpaceX could probably do the same if they run SpaceXnet in parallel with TCP/IP and sell their own hardware (or do a TCP/IP over SpaceXnet protocol that they use between ground stations)
