What do you mean when you say building crud apps should be automated?

CRUD apps are ridiculously simple and have been in existence my entire life. Yet it is surprisingly difficult to make a basic CRUD and host it somewhere. The bulk of useful but simple business apps are just a CRUD with a tiny bit of customisation and integration around them.

It is true that LLMs make it easier to build these kind of things without having to become a competent programmer first.

conventionally, it should have been abstracted by a higher-level language.

E.g using Rails and generate scaffolding. Makes it real fast and easy to make a CRUD app.
