I also cringed at the look of this. I have a bunch of old books I would like to digitize, and most bookscanners I come across require you to at least spread open the book completely, which would, as you say shred them... And they don't even involve vacuum, movement across sharp edges, and stepper motors...
It definitely would. And probably some that are not damaged when something gets jammed or the environmental conditions change and react with the paper. But if you’ve got a mountain of books to scan and you can do the bulk of them with a machine like this and then use a more careful approach for the special cases, that’s a win.
