Agreed. He should provide a graphical solution to every example given. It's distressing that none are given, not even then ignore-exception piece. That's the brilliance of Bret Victor's essays: he posits the idea, bringing you along in the 'yeah, that's been bugging me, too' fashion, and then proceeds to guide you through working solutions that build on themselves over the course of the piece. If you've been properly dog-fooding, show us the crumbs and the empty bowl to prove it. Graphical wrappers to plain text are not only 'orders of magnitude harder [to implement]', but that much harder to debug as well. If your GUI client to a remote server beach-balls waiting for a command to complete, is your code wrong, or your connection latent, or your desktop app crashing? An SSH connection to the CLI server can cut through a lot of that pretty quick.
