ControlAI has launched an official campaign in Canada, with 33 politicians across party lines backing a clear statement in favor of an international prohibition against developing superintelligent AI: https://controlai.com/canada-statement/en
I used to be ambivalent about government intervention wrt AI safety, because politics can screw things up. However, it seems clearly positive to me now: the development of superintelligence impacts the whole human species, and as such, the democratic process should have a say in whether (and how) superintelligence is developed. Governments have been tolerant thus far, but the general public is not so happy about this, meaning that political campaigns have a good chance of success (in my estimation). Without such government intervention, the AI industry is on-track to develop superintelligence within the century if not the decade, and I do not believe safety research is ready to handle the risks. As Yudkowsky put it, only law can prevent extinction.
Public reception of this campaign will make a big difference in the willingness of further politicians to endorse this or similar statements. Although I would normally hesitate to put signal-boost-style politics on LW, this could use a signal boost, and is quite relevant to the audience here.
I talk with Samuel Buteau regularly and he has described how he talks to politicians in some detail; he is always focused on x-risk and has described specifically putting effort into convincing a politician NOT to conflate x-risk with other issues. I can’t vouch for everyone at ControlAI, but I trust Samuel quite a bit. Samuel is (by far) the main ControlAI person behind this campaign.
