No, I definitely agree with this. Scheme is a valuable pedagogical tool.

But that probably doesn't matter. So it's better, on the whole, to preserve what you can out of the current book by adapting it to Python than losing it completely.

Things will get lost in translation and substantive changes will have to be made. That's why writing textbooks is a creative endeavor rather than just updating the English used in older texts.
