Remember the days of semantic markup and the CSS Zen Garden? When you could actually read and understand a web page's source? Now we have these javascript behemoths that are as clumsy as they are stupid.
I have a feeling we are in for a renaissance of simplicity, and its going to start with a page, and end with a page. Pages are scalable. Google has like 50 billion of them. Pages are nice. Now do me a favor and kill off react.js and every walled garden like Facebook.
Can we please just fix them from the inside? If you're an engineer at Facebook, why don't you take it upon yourself to actually do something about this mess?
