I've thought about getting a web browser to work on the terminal for a while now. This is an idea that hadn't occured to me yet and I'm intrigued.
But I feel it doesn't solve the main issue of terminal-based web browsing. Displaying HTML in the terminal is often kind of ugly and css-based fanciness does not work at all, but that can usually just be ignored. The main problem is javascript and dynamic content, which this approach just ignores.
So no real step forward for cli web browsing, imo.
