Thank goodness technologists don't abide by that principle. There is no question we'd be living in trees.

As for the gaydar, there are serious methodological questions about how the network was trained; at worst, it was tested on a set of images that overlapped significantly with the training set. An absolute no-no in AI, because in this instance all you'd be doing is getting it to recall faces. Not quite the claim they were making.  

So I'd suggest the principle that needs to be reasserted for scientists, is that their contributions should be a) useful, and b) actually work.
