It's even harder to understand this width advance of modern web technologies. In 90th you had single channel to download unoptimized GIFs and websites used to be built from these images. Now you bundle, minify and gzip all these stylesheets and scripts which are capable of 1000x what you did back then, and then load (usually precached) analytics script from CDN while fetching mp4's in parallel and streaming them on the fly. It's just bad developers. Facebook takes about 100ms to load everything (but still has shitty ui). And they build tools so everyone can do this too. And developers now brag how complicated web is.
