It’s not, though. It seems to be a very shallow understanding of the subject (or just insufficient consideration?) stated confidently (as so often happens these days). As a sibling comment to yours also points out, there are plenty of examples to the contrary - models taught to recognise text from indistinct images. We’ve all been contributing to this for years via Captchas, and now we’ve got to the stage where our iPhones apply the concept locally to text found in our photo libraries.
