`next build` makes a server that needs to be run with nodejs. Dynamic pages keep being JS code. the fact that some pages are optimized down to html is an internal implementation detail. `next export` makes a folder of static resources (HTML, packages client JS code, CSS). It also forces every page (even dynamic ones) to compile down to HTML.
