Ironically, one of the original major reasons WordPress became popular was its dynamic nature. It dethroned Movable Type, which was an extremely powerful and extensible static site generator.
It's wild to me that this post's timeline makes no mention whatsoever of Movable Type, and at one point it links to another author's post titled "A Complete History of Static: The Beginning to WordPress Headless" which also makes no mention whatsoever of Movable Type. Now I feel old :/
To my surprise, Movable Type is still being developed even today. Wonder if there's some companies still using it out inertia. I know many moved off of it back when they restricted their free tier
