The modern analogue of 4GLs would be the promise of LLMs letting you write prompts so you don't have to learn a programming language; the promise of the original 4GLs like Pearl (not to be confused with perl) and Objectstar was to let you have non-programmers writing business logic without being COBOL or FORTRAN programmers.
Ironically, the whole reason COBOL has its weird-ass syntax was to let you have non-programmers writing business logic without being assembly or C programmers. We can see how well that worked.
