The OP's comment is very good because the discussion in the article is quite misleading about what they accomplished. It's also apparently self-serving; apparently marketing material for Wolfram. As your sibling's post makes extremely clear, classifying handwritten text from the Edo period is a much, much, much more difficult problem. In fact the samples they have taken for training are so unstylized that they might just as well have done an article about recognising modern hiragana hand writing. That would be very cool too, but would have gathered no interest because it is a well solved problem. I have no problem with people doing fun projects and explaining how they did them. I have a bit of a problem with people apparently making exaggerated claims about their product's capabilities.
