Network functions

If network for the multiplayer is going to become obsolete what are the alternatives?

@kanderson5 multiple alternatives exist, 1 of them is proposed by unity the “Unity connected games” Game Development Software: Build a Multiplayer Game | Unity
while a 3rd party option still exist such as Photon Photon Unity Networking Classic - FREE | Network | Unity Asset Store
Obviously you can still find other 3rd parties or build your own
