[Question] Suppose $1 billion is given to AI Safety. How should it be spent?

What are the current bottlenecks in AI Safety progress, and if they were solved with money, what would be the next bottlenecks?

Do current researchers need more money? Do we need to catalyze the creation of more researchers? Do we need to alter public opinion? Something else?

If you had $1 billion to spend on AI Safety, what would you do with it all, from start to finish?
