> when people were trying to do something else, and had to invent new tools.

(Author here.) My point was not that you shouldn't invent tools if you need them. By all means, go ahead. My heart beats for creating tools (especially tools to create other tools...).

What I wanted to express was this: if you want to write _a book_, first write the book and only then worry about the tools. If you then notice that you need a custom toolchain to get the book in exactly the shape you need it to be, do it.

I've had people tell me that they would love to write a book, but, well, the existing tools are not sufficient enough. And I think that's the wrong approach to writing a book: write something and you'll quickly realize that the tooling is not your biggest hurdle.
