It can't be abstracted away, but it can be abstracted and raised to a higher level. Not all logic can in all cases, of course, but you can certainly abstract many cases of domain-specific logic to something higher level that you might be able to represent in a low/no code system.

Higher level building blocks still need logic to assembled just the same. If they don't, they are just configuration. That's why in every one of these use cases of these "no-code" projects, they ended up hiring programmers to build it/keep it. And then the programmers spend the rest of their days cursing whoever built the system which ties their hands.
