Not sure if I can agree with that.
I would say that most of the internet is static by definition, even my blog is a static page with some CDN to make it faster. Most of the news pages are static, most of blogs should be static, most of the e-commerce should be static (the product page is static, not the purchase itself),
You may live in a place where internet is fast, but the majority of the world still breaths in 3G, with unstable connections and a miserable experience, so a 10mb page (I’m looking to you stupid Discord), could be a 1mb page, if wasn’t the bloat.
