Semantic HTML made sense in the early 1990s where it was intended for formatting static academic literature. It hasn’t made sense since about 1998 however, but unfortunately no new paradigms have emerged to allow creators to express emergent state web apps, which is almost the entirety of content created for the web for the past 25 years.
