A lot of expected pessimistic HN comments that seem to miss the point here. I think SSG's are pretty damn good, I use Astro. People seem to think that SSG's forces you to use markdown or something, they don't. It's literally a mechanism where content from somewhere is turned into static pages. You can even use Wordpress and it's API as the source of the content for a SSG.

In my case I use MDX, which is Markdown that allows components (eg React) to be embedded. This is great for interactive content, articles with charts, visualisations, etc.
