I think that there <i>will</i> be a new successful browser one day - and it will be disruptive. But it needs two properties:<p>1. A unique use case or feature that cannot be easily implemented in the existing browsers. Something that breaks the current architecture and turns the current use cases into afterthoughts. ("oh, yeah, right we actually need to render html somehow at some point, can the intern do it?")<p>2. A significant breakthrough in software engineering productivity, a major step in terms of abstraction <i>and</i> safety. Something like the combination of a LLM and formal methods.<p>This browser does not check these two boxes (using C++, albeit hopefully a more modern dialect, and targeting plain old browsing). So it is certainly great for the spec - and should be paid for by the W3C, IMO, great for the people developing this as an exercise, but it will never dethrone Chrome.
