I wouldn't say so. The 'Learning by mistakes' step in the demo shows that the AI can work through these issues, presumably this can be done more efficiently than a human.
The learning from mistakes part of the example is – you tried /port_wines but the path is /wines/port instead. But what about if the path is actually /beer and you have to pass a hidden undocumented query parameter called ?wine=1 for it to give you wines. But then the response is still of Beer objects (because that's the only thing the API validator would allow), so you have to map all the Beer fields to their equiva…
If you let the AI both create the API and use it, you can avoid the problems humans create.
