Figurehead and branches is an interesting idea. If data, code and workers are located all over the world, the organization can probably survive even if one or few branches are taken. Where should the head office be located, and in what form (e.g. holding company, charity)? These type of questions deserve a post, do you happen to know any place to discuss building safe AI research lab from scratch?
Any computable intelligence can be considered scaled-up human intelligence, because humans are smart enough to follow arbitrary programs, just very slowly. Since many organizations can do a lot more than what a normal person can reasonably accomplish in a lifetime, I think it is appropriate to call them superintelligence.
If a new non-profit AI research company were to be built from scratch, which regions or countries would be best for the safety of humanity?
