> Natural language can be translated bidirectionally with any programming syntax.
Sure, maybe, but it's a lossy conversion both ways. And that lossy-ness is what programming actually is. We get and formulate requirements from business owners, but translating that into code isn't trivial.
The lossiness and iteration you describe still happens in natural language programming, you're still clarifying requirements, handling edge cases, and refining solutions. The difference is doing that iterative work in natural language rather than syntax.
