if someone is actually interested in using AI to understand a story you don't just feed it pages you use OCR to pull out the script and feed the script and then use the drawing context to correct the rare mistake or give it context on ambiguous wording. yeah people will rip on this too but I can read Japanese not horribly (my anki is at about 5000 cards, I've read some novels JP) and it does quite well like this since it has continuous speech. If the people pumping out the AI shit actually did this 99% of people wouldn't even notice.
wow I didn't know there were tools to rip the text from images. As you say, that does solve the problem I saw from my testing where AI didn't have the full context and continuity of the story and actions. And yeah, if people uploading AI took the time, only full-time translators would notice but the vast majority who are just hentai enjoyers will not notice.
