My own take on this: the article talks continuously about the price of software, but misses the point of quality. If price was the only variable, then software development in US/Europe would have been wiped out decades ago in favour of software development in cheaper countries. It didn't. Manufacturing was delocalised, but development (the thinking/designing part) stayed.
So the question really is: can AI produce software of the same quality as a person? Can it be equally reliable?
