Excellent article. I suggest finding a different, more informative title if you want to appeal to the EA forum audience though. 

We might be able to solve whole brain emulation before AGI arrives, and then upload alignment researchers who can do research 1000x faster than existing researchers. This is also risky, because (a) the sped up humans could disempower humanity by themselves and (b) these humans might accidentally build an AGI or do capabilities research. 

WBEs are aligned intelligences (in the weak sense of not killing all humans). Once you have WBEs, wouldn't you directly move towards a pivotal process first, before trying to solve harder versions of alignment?

I'm also guessing 1000x is a dangerously fast speed to run digital minds when you're not confident you have good oversight processes for the minds.
