That was always the pitch of higher level programming. Pseudocode is slightly more of a spec than compilable C; C is slightly more of a spec than assembly language. It gets advertised as being "all you have to do is write a spec" and then it becomes just programming later.

Regardless, the studies have already demonstrated this: As you go higher-level, you write roughly the same amount of code and bugs per line, but also implement more features per line.

An AI tool will be ready for use when it demonstrates that same capability of "same bugs per line, more features per line".
