Hypothetically, would you rather have:

1. AI is not delayed, but the strongest AI, 10 years ahead of everyone else, is in the hands of a single very powerful multinational inter-governmental agency
2. All AI delayed by 10 years

Hm... It seems to me that the first option is better, since one high-quality product stimulates competitors to develop, not to sit still. Even if it is so powerful, analogues will still be built. Healthy competition should generate strong competitors that benefit the end user of the product.
