If I know anything about the future, it doesn't look like the present.
The web won't look like it does now in 2050, and neither will the internet.
But it might very well be built on webassembly on browsing engines cum operating systems on top of hypervisors on top of verified microkernels, and the web will probably be delivered on top of HTTP/2 on top of TCP/UDP and so on. The layers probably won't change that much.
