What are the most impactful roles that EAs are currently not entering (and why)?

I think the problem is that unethical people have an insurmountable competitive advantage in getting jobs as an ethicist. At least if these are academic roles, you have to publish to be a viable candidate, it's a lot easier to say a new and false thing about ethics than a new and true thing, and reality won't slap you in the face for being wrong the way it would in science. So you'd probably need to aim to be able to influence the hiring process somehow w/o being subject to the perverse incentives. 

I like this idea, and am also curious about whether they would be able to influence trajectory and what that might look like. 

Would the MO be to directly influence tech & bio leaders? Or indirectly influence them by getting citizens interested and applying pressure?

 I find ethics critical, but unfortunately am not sure how engagement around ethics could be enforced for  people who don't grok the importance. Maybe that's where governance and treaties come in.
