I don't believe the dev is milking, I'm just making this clear before this is interrupted as a hate comment rather than a question.
I understand that AI isn't perfect and If the dev has already experimented with it and It only made things worse then that's completely understandable. However, surely the fact that he's already been translating for several weeks, it might even be close to a month now ,and needing a further 6 weeks needs to be changed/fixed somehow. Taking 2 plus months on translation alone almost makes it certain that the games never going to have more then 1 update a year unless the update size is slashed in half which might just end up changing it to two updates a year that equal the singular big update.
I feel like the only way to push the progress of the game is to out source the translation to someone. I honestly think several fans would do it for free but even if it was paid for the dev makes a decent monthly amount from the game that can go towards it. If the dev is very particular about how he wants scenes to be translated/interrupted then he could do the more major scenes of the update to make sure they come off the way he intends. Obviously there would be vetting process that I'm sure would turnout someone he was happy with and hopefully he would trust them to do the more major scenes as well, which could leave him to just touch up and fix a couple of things at the very end.
