According to this piece, less than 0.1% of Japanese people can read くずし字 (kuzushiji), old cursive writing (both kanji and kana) from the Edo period. So a smartphone app, powered by AI, will help people decipher any old documents they may find in their houses (or their parents' houses - the article mentions it's quite timely to be released in the new year, just as everyone is going back to their parents and families over the new year period).
While this is interesting, if you're struggling to learn modern Japanese and kanji, your first reaction to seeing this may be "what fresh hell is this!?" ?
