As far as I know, there is no good one, and this is a moderately-sized oversight by the rationality/EA community. In particular, there is no census of the number of people working on each AI alignment agenda. I want to create one as a side project, but I haven't had time. You might find the following partial data useful:
As far as I know, there's nothing like this for the rationality community.
Also, the State of AI Report 2021 has a graph of the number of people working on long-term AI alignment research at various organizations (this graph is from slide 157):
As part of the AI Safety Camp our team is preparing a research report on the state of AI safety! Should be online within a week or two :)
There is a Google Sheet that lists many of the people working on alignment and some basic information about each person and their work. It's not supposed to be shared publicly, but I've sent it to you in a private message.
I'm new to the Rationality / EA community, and I've been getting the sense that the best use of my skills and time is to try to contribute to alignment.
Currently, my focus has been guided by top posts / most often mentions of names, here on LW. E.g. "I see John Wentworth post a lot. I'll spend my time investigating him and his claims".
The problem with that is, I have some instincts developed in large communities that gives me a sense that everybody is already working on this, and that if I let my attention roam the natural way I am going to end up in a big pool doing duplicate work as everybody else.
Is there anything here on what demographics are working on what problems?
