I like the part where he mentions why using a traditional GUI tool is more difficult than using an expressive language with basic syntax.
"But in photoshop, I instead am relying on the problem being solved externally ("ok, how can I find the right menu that deals with this kind of operation? what's the word the designers of photoshop used to describe this... I hope if I google it in plain text it might link to a forum post or something of someone with the same problem?")."
This is valid for most cases when GUIs are harder to use than a CLI with syntax.
