The current tools were created by generations of scientists and engineers; people that these linguistics communities lack. As some of them get educated in NLP and related fields, more resources and corpora will be build. But heck, even languages for which there is universities and labs working on it (plus EU funding) there is a huge gap. For example czech. As a side nodes, some existing researchers who have an interest in other languages start work on them even if it’s not their native language. I know researchers who did that with african languages: by working with students speaking them, there is transfer of knowledge and preliminary work done. Mentoring the first generation of native speaker scientists is the key imo.
