What I'd like to see is how it handles any kind of more complicated tasks - e.g. one where you need to build two or three layers of abstraction. Or one where you build domain objects that are used by other tasks. Or even one that showcases error handling.
You can get something similar, minus the fancy NLP processor, in Unreal Engine, via its Blueprints feature. Suffice it to say, there's a reason people end up learning and switching to C++ the moment their problem starts to involve any kind of complex logic.
Note: I'm not against improvements in programming experience, and more visual and interactive paradigms. But I've also played with enough dataflow languages to fully internalize that there is irreducible complexity in programming (that comes from it being an art of micromanaging possible states), and it's painfully hard to work with it in a flowchart form.
Does make me think programming can be radically different and maybe a lot easier
