Honestly for visual programming scratch is really great to get kids or even adults to learn scratch, since it’s basically the exact same thing, just easier since you don’t have to worry about syntax.

Stuff like the unity block system is also extremely powerful, and lets designers configure, say, a characters movement much easier.

MDA, honestly I don’t know much about it, but from the description in the image it sounds like it still requires someone to “write a universal model”

I think the idea is that someone at the company could just take an already existing model and deploy it, not sure though.
