This article basically says that a text based application (turbo pascal) is smaller than images and PDFs. Obviously.

It's a full compiler and debugger. It's not at all obvious that it could be smaller than an image.

“Obviously”. Look, if you don’t really know what a development environment is, that’s okay. But a dismissive comment such as this makes it obvious to the rest of us that you don’t know, when I’m confident that isn’t your goal.
