Radical Suggestion: Use Completely JSON in webpages/browsers. better than HTML

We are using Json in many "data presentation" tasks. Why would it not be the case for creating/displaying webpages ?
I make a Radical Suggestion: Use Completely JSON in webpages/browsers.
That is, a website should be presented in JSON (like named array), browser (including engines, renderers) should interpret and show pages from these json data. This would speed up many development and parsing needs.. Many computer/processing/energy power may be saved worldwide.
- webservers (including interpreters like php/python) would be faster, bc preparing a webpage would be much faster.
- Browser (engines, renderers) would be faster. No need to parse, prepare Dom, show all elements on gui... all would be faster
- Crawlers: would be much faster. no need to parse html and construct structured data... All in already in json.. All processing power is saved...
- Apis: All apis would talk directly to webservers or each other.. Api's and webservers would talk to each other directly. This would increase a lot interconnectivity of services.
- Web development/human tasks: Developing/editing/debugging webpages would be much easier with json. almost infinite possibilities with json named attributes. All attributes, styles, classes, would be easily representable in a consistent unique way. No need to memorize/use different notations/format specifiers for each property.. Everything in json named arrays, attributes..

Using this method in representing information/web in Internet, Millions or even Milliars of Dollars would be saved, bc processing power in every Tech device, servers, computers, notebooks, mobile devices etc.

That is, I am suggesting replacing HTML with json. We may call this Json Web, or simply JWeb. No more html.
In this case, we need only talk about json representation standards of page elements, such as text, image, video etc. Actually, All sides of Internet (browsers, servers, engines, users) may support multiple standards easily.

I will improve this article by giving examples.
very simple example:

{
"header" : {
"title":"First JWeb Page"
},

"body": {
"div": {
"p": "Sample Paragraph text"
},

"table": {
"styles": "....",
"rows": [
["val1", "val2", "val3" ], //row1
["val1", "val2", "val3" ] //row2
]
}
}
}

The more beautiful version can you find at: https://jsfiddle.net/u2hyvx6s/
(If somebody knows to display this here in Drupal, let me know)

This idea can be improved. Every element may have its own style info or any additional info that is required.

You see a "rawdata" section at bottom. With the help of that rawdata/json section, any robots, parsers can directly use data in this "json representation"

That is what I mean, json represented webpage.
Browser, Api clients, devices etc... all can directly get and use such data. No need to parsing, even no need to dom representation. A (properly structured/planned) json data, can have all info.

I will in future try to write a server and client that works in this logic.
A json webserver is actually a Rest Api server. That is already possible/ready.
All I need a basic browser code, that reads from json, instead of HTML.
