I don’t think there’s a main single technical issue with web. But if it counts, I’d go back and put less sleepy people to rule web standards. So that they could sit together and clearly see what it lacks fundamentally and add it there instead of waiting for ten years for each feature. Also they would just expose lower-level interfaces, so things like flexbox or content queries could be implemented by simply hooking up js callback into a sizing loop, etc. As if they were proper programmers and knew that a generic solution is just better than a bunch of specifics from the evolutionary pov.
