This seems a hard thing for many if not most devs but even in the most hardcore software company most employees are not devs. If anything the smartest people in your org are not the devs (unless you’re FAAnG). Any tool that puts more power into the non devs is a great tool. Any person managing a company that needs to string apis together and perform high touch service would need a tool like this. Now why this tool and not any other RPA is a different question.
Look at the examples though. See the second one. In the animation, it shows the dot distributing the different values within a response, as though it's some parallel task. Outside of that it's serializing an array on time for no reason I can tell. That's like the Jump to Conclusions Mat in Office Space...
I think not. It seems like Yahoo! Pipes. It's cool but I don't see most devs using it. And FWIW Scratch is way cooler.
It could still be nice but that's exaggerating it a whole lot, I think.
