open source licence obligations are almost always triggered upon distribution
and cloud software-as-a-service doesn't count as distribution (except under AGL and a few rarer less-used licences), because the software never leaves machines owned/operated by the "author"
so, cloud SaaS has been able to consume open source code without contributing anything back for decades already
AI-generated bespoke software might be killing SaaS, but it'll like never trigger open source obligations either, because it'll never leave machines owned/operated by the "author"
so these AI-reimplementations of existing open source software are kinda' pointless
