There are communities today who, by policy/choice, have been extremely selective in adopting modern technology, the Plain People (Amish et al). I’m not sure if that model would scale up to “uses all tech except pledges to not use advanced AI”, because the unifying thread of religion has a somewhat unique level of power that mere commercial pledges seem to not have, but it would be worth looking into the existing practices as a potential model and trying to project the good and bad that would come from it.
