You know Gaudí? He was a great architect, and made great constructions visited by millions, like Casa Batlló, Casa Milà, or la Sagrada Familia.
To be fair he didn't place a single stone, and la Sagrada Familia was finished long after his death.
So yes, I believe you can make products using LLMs.
If there is a line, it's definitely between "I designed the architecture, and decided on what each class should do, before letting AI do a single line" and "I told AI to clone twitter as is".
Although the latter could be akin to kids colouring books. "I made AI clone twitter, but painted it red and called it rettiw." As long as there was some decision or a modicum of effort it's "ok". We can let them have their victories and try again.
