I first started using SSiWelsh around 2011 or 2012. I’ve lurked some years, participated greatly in the community some years, and have even had the pleasure of meeting Aran and some other wonderful SSi folk in person. I can genuinely say that Aran and the team are some of the most passionate people about preserving vulnerable languages.
Just because the team isn’t ready yet to disclose fully how things operate in a way that satiates your petition, that’s on you to wait and work with them. The fact that 75%+ of the languages being prepared will be available for free shows the dedication that the team has in preserving, extending, and making available quality language courses.
I am not a fan of AI myself (I only use free and open weight models myself, and only somtimes). That said, the current iteration of SSi is a work in progress which means that the technology stack is also a moving target. It’s hard to be fully transparent when the stack itself is evolving, one might want to get their “ducks in a row” first before further transparency. I also know SSi is co-developing a means for volunteers to assist and fill in the gaps where the AI cannot. I think that’s a wonderful compromise. I also know (because I lurk) that SSi is partnered or has worked with Irish language advocates in positions of power in Ireland. I think as the relationship evolves, with relation to Irish specifically, you will most likely see a pivot to something that is more akin to your taste.
Perhaps some patience.
