I think this is only partially true. There are aspects of coding which can be abstracted away, either because they're essentially boilerplate or because a simpler description of the solution is sufficient. Ideally if a more complex description is required, one can drill down into the simplified low-code description and add sufficient complexity to solve the problem.
I mean, couldn't many of the existing frameworks be described as low-code wrappers around more complex work flows and concepts?
