> It makes no sense to me. You are saying, that instead a 5 kB webpage, you would load 50 MB code, which emulates a browser, just to show you the same webpage?

Have you not worked in tech long? One of my 'favourite' things about one tech stack I once worked on was that someone decided to implement a file-system inside the a database that is stored on the file system. Even better, the database itself effectively just reimplements the features of a database.

So we have a file-system storing a database that exposes a completely different database that holds a file system.
