You can always build a transition infrastructure on the top of IP, like https did by coexisting with http, and a bit like gemini does (it has https://gemini.circumlunar.space/ https://gemini.circumlunar.space/ at least). Then build some links without it, and have the compatibility layer the other way. If there are compelling reasons to use the new protocol, it might gain some traction. Maybe we'll turn off IP, but probably not within a century, unless some organization acquires a tremendous amount of control over the Internet.
