It would be nice if someone came up with a "network VM" that could run sandboxed code that was more like traditional native applications, but seamlessly networked to a server (like Erlang or Phoenix LiveView on multiple nodes but simplified for server-client). Then it would be possible to write more standard apps on a well designed, purpose-built system which would simplify a lot of Dev work. Then you could have a well designed markup language for easier building of documents too. But start fresh in a VM system with all the hindsight of what purposes the web is used for, and the layout systems that are most flexible/popular. You could have some low level thing like web assembly (or even just we assembly itself and get all of the current optimization and standardization work for free) that other languages compile too. And a low level GUI library like Vulkan that you can build libraries on top of.
