For archiving, some cities still have pen drafted mylar that sits in vaults. If you want to revise plans, go to City, check out the mylar with your life, use a razor blade to edit, pen with permanent ink and send back into the vault. New plans are plotted, but still to mylar.
With kids I am curious if they will learn how to handwrite. Will schools even teach how to read handwriting? Some interesting stuff as more goes digital and type printed.
Pen, Pencil, paper still has very great uses.
