It seems you only need to recruit one billionaire (or someone who succeeds in becoming one). You've already done your part to raise the probability of achieving that pretty close to 1 (I wonder how many readers of yours would OVERfund you if they became billionaires? Here's one.) I don't think you need to sell FAI or the Singularity any more. You can move on to implementation. The universe needs your brain interfacing with the problems, not the public.
