Well, Cahill has his opinions, Ripon has hers. Obviously there is a controversy on this issue, between experts on the matter, and I am not equipped to resolve it, or even to know who is representing some kind of consensus opinion. Basically, I know a couple of things about computers. I don't feel I have the knowledge to weigh in on any other scientific subjects.

That said, I have to observe that if the matter was settled the way Cahill claims it is, Nature wouldn't be publishing dithyrambs for Ripon's book, and Cahill wouldn't be publishing his own article on Quillete. It would rather be the other way. It's Quillette that's know to court controversy and Nature that's know to be as controversial as a pot of instant noodles.
