That said, if you can't imagine current AI progress leading (in 10, 20, 40 years) to a superintelligence, or you can't imagine a superintelligence being dangerous beyond humans' danger to each other, you should realize that you are surrounded by many people who can imagine this, and so you should question whether this might just be a failure of imagination on your part. (This failure of imagination is a classic cause of cybersecurity failures and even has a name: "Schneier's Law" [1])
Balancing these two priorities of protecting basic rights and averting the apocalypse is challenging, so the following is probably the best humanity can aim for:
Anyone should be able to create and publish any model with substantial legitimate uses, UNLESS some substantial body of experts consider it to be dangerously self-improving or a stepping stone to trivially building something that is.
In the latter case, democratic institutions and social/professional norms should err on the side of listening to the warnings of experts, even experts in the minority, and err on the side of protecting humanity.
