The idea of an interface is fundamental to computing. No matter what you do, at the end of the day data exchanged between two systems has to be structed _some how_. E.g., machine code submitted to the CPU, register configurations, C ABI, Python structures, JSON. You _could_ be hand wavy about it, maybe even use machine learning, but then it will just be ambiguous and lead to vulns. IMO the constant insistence to try and find ways around this is a huge setback. I used Python heavily in 2008 and always was annoyed when trying to figure out the essence of an API (which is what you get when there is no concrete interface). Whenever I read a Python codebase, unsurprisingly, it's full of handwaving and the resultant bugs (some people know what they're doing, but the problem is there more than in a typed language).
