I'd say the progression from machine code to Python is a fundamental improvement. For simple cases, I think a visual/textual code interface is possible, but for any complicated case the visual interface will become inscrutable. Maybe an optimal tradeoff is like how game engines allow scripting languages to live on top. A number of 3D engines use this paradigm with a visual language in place of scripting language.
