It's an awful idea, notebook stability ages like milk

i think that's true of almost all tech books in paper form

personally i think these work great because i can add cells to inspect data or try experiments easily as i'm reading to help me understand whats going on

What do you mean by stability in this context?

I think he means they bit-rot. Stop working.

read for theory and big patterns

These sorts of books have existed since the dawn of notebooks. While I think them useful for demonstrations, I don’t think there is much pedantic value (beyond a more static medium) in all honesty. Well-worked examples a student can consult while attempting to solve problems on their own is still of paramount importance.

When you say "pedantic value", do you mean "pedagogic value"?

Why can’t we have both? Great examples AND an interactive, reproducible medium?
