Have you seen the "Stop drawing dead fish" and other Bret Victor talks? Those are not high level tools, they allow you to build generative animation and graphs from scratch.
Photoshop-like visual tools are indeed limited to pre-built concepts, but Victor has found a way to make coding possible without textual syntax; that's a powerful idea that may be the basis for a tool allowing artists to program without requiring the programmer's skill to keep the parse-tree-plus-AST in your head while building automations.
Take a look at the topic of End User Development and Programming by Example[1], it's a quite comprehensive research field dealing with ways that programming-like activities can be done without any traditional "raw coding".
