Those might seem like trivial differences but plenty of things go wrong there, plenty enough that you can't just use a library instead of a programmer, and then they are plenty enough of such errors that vibe codin…
I think the point being made is that even though the specific set of requirements may be unique in a stakeholder basis, all the components already exist, and have been combined in many ways. So it really boils down to prompting in such a way that the right set of components are brought together in the right way. That's where the skill now lies.
And how is this different from just calling the libraries in the right way to make it adhere to stakeholder requirements?
The statement isn't "its impossible to get an AI to print the code for a right program", but "the work and skills you need to get an AI to print the right program is as much or more than to do it yourself.". That seems to be true for all but trivial programs. Here trivial means you can download a git repo and change some variables to get that result.
